PROPAGATION ISSUES IN DIGITAL MICROWAVE RADIO LINK ENGINEERING

PROPAGATION ISSUES IN DIGITAL MICROWAVE RADIO LINK ENGINEERING PDF

This Course covers the main topics in Radio Propagation, with application to the
Engineering of Digital Radio-Relay Links. The aim is to provide the radio engineer
with the basic knowledge and understanding of radio propagation phenomena and
their impact on the operation and performance of digital radio systems.

The Course makes reference to fundamentals in Radio Propagation Physics (without
need of complex mathematical tools in Electromagnetics theory). From this, it derives the
basic concepts in Radio Link Engineering. A detailed presentation of procedures
and computer tools for the Engineering and Planning of Radio Systems is out of the
scope of this course.

The Course User is assumed to be familiar with elementary notions in Digital Radio
Modulations, Equipments, and Systems, as well as in Interference Analysis and
Planning and in Regulatory Issues. Some topics in the above areas are discussed, but
only in connection with propagation aspects.

It's Better to Make Mistakes Than To Be a Perfectionist

It's Better to Make Mistakes Than To Be a Perfectionist

Some people waste their lives trying to avoid making mistakes, but cripple their careers since perfection isn't attainable. They ultimately make fewer mistakes but accomplish less because they waste so much time trying to make things perfect. Time is money in business. Doing a good job today is more profitable than doing a great job tomorrow.

Rock star Jon Bon Jovi's career might have ended before it started had he not understood this principle. He was only 21 when he won a contest with a radio station to record his first song in 1983. He quickly formed a band and released a debut album that went gold the following year. Suddenly they were opening a concert for ZZ Top at Madison Square Garden. They were rushed to record a second album and strike while the iron was hot. It was released in 1985 to poor reviews. Jon was unhappy with the album and wanted to do better, but timing was critical. The band moved past this bump in the road and released a better written and produced third album in 1986. Jon still wasn't happy with the album because he didn't think one particular song was good enough to be included. Fortunately for him, he listened to the people who knew the business side of music. That song was “You Give Love a Bad Name�. It became one of the band's most well-known singles and helped send the album straight to number one. This launched them into super stardom and they went on to sell more than 100 million albums. Had they waited until the second album was perfect, they might have lost the support of their record label before they got to the third.

This is what happened to rock legend Tom Scholz. He's often referred to as the smartest man in the history of rock and roll. He holds a masters degree in mechanical engineering from MIT and is listed as an inventor on 34 U.S. patents. The 1976 debut album by his band Boston sold over 16 million copies and remains the biggest selling debut album in history. It's also considered one of the best-produced albums in rock history. Scholz played every instrument on every song and produced the album himself. He's brilliant and talented. He's also a consummate perfectionist who took eight years to finish the third album. CBS/Epic Records got tired of waiting for it, sued him for breach of contract, and dropped Boston from their label.

It's okay to have high standards as long as they're realistic. It's not okay to procrastinate until everything is exactly the way you want it to be. Your employer doesn't have time to wait around until you get things perfect even if you are a genius inventor or legendary rock star. Deadlines must be kept and payroll must be met. An electrical engineer who attended my management seminar in Orlando once told me that he has to constantly remind the engineers he supervises that sometimes 90 percent is good enough.

Highly valued employees don't necessarily make fewer mistakes than run of the mill employees. In fact, they often make more mistakes because the number of mistakes increases as productivity increases. They just know the right way to do it. Making mistakes is okay as long as:

1. They âre reasonable mistakes to make.
2. You catch your own mistakes.
3. You correct your own mistakes.
4. You accept responsibility.
5. You don't blame others.
6. You don't make excuses.
7. You don't hide your mistakes from your boss.
8. You learn from your mistakes.
9. You don't repeat the same mistakes.
10. You apologize when it's appropriate.

Opportunity-A must read

Dear All,

I have come across a wonderful story on opportunity which struck me with it's simplicity and similar kind of truthfulness.

Once upon a time there was a young man who was longing to marry a beautiful daughter of the village's most intellectual farmer. He approached him with his wish and showed the readiness to accept any challenge to win his heart. The farmer smiled and asked him come to his farm next day.
Next day the Farmer put a simple condition in front of him that he would leave three bullocks open in the farm and he needs to catch the tail of any one of them. If he succeeds in that he would be eligible to ask for his daughter's hand. The young man laughed in his sleeves and started dreaming about her marriage with Farmer's daughter. The Farmer released the first Bullock which was very healthy and full of wildness. The young man had never seen such a big bullock in his life hence he decided to skip this one and wait for another one to catch the tail of. Bee lying his expectations the second one was much bigger and stout like a hunk. He decided not to play with danger and skipped the second one also. Now, as the last chance the third bullock was freed by the Farmer which brought the huge smile on the young man's face. The third bullock was apparently very weak and thin. The young man ran towards it and jumped to catch it's tail but he was shocked to see that it didn't have any TAIL.

Life is full of opportunity. No doubt some of them are difficult to take on but if we let it go due to fear or lack of self confidence we may never be able to marry a beautiful women of farmer called SUCCESS.
