For reliable and error free transmission of data in communication systems we require a system employing forward error correction schemes. This paper analyze the performance comparison of Convolution code, Reed-Solomon code as well as concatenation of Convolution code and Reed-Solomon code over optical communication links with interleaving in terms of their probability of Bit error rate and signal...
The optical uplink, ground station to satellite, is more susceptible to signal fading compared to the downlink channel due to beam wandering experienced at the transmitter in the ground station. Alamouti space time codes have been used to partially mitigate this handicap. With the use of these codes, a bit error rate(BER) of 1 × 10−8 can be achieved for a link margin of 6dB. A transmitter beam radius...
There is an increased emphasis on the use of digital techniques in all aspects of human life today. Broadcast radio and television, cellular phone services, consumer and entertainment electronics etc are increasingly using digital signal processing techniques to improve the quality of service. Transmission and storage of documentation and images pertaining to patient records cannot remain an exception...
