Abstract:

The subject of this trade study is error control techniques. The purpose of the study is to determine the optimum error detection andor correction techniques for DCDRS. The objective is to increase system reliability, improve anti-jam performance, reduce the probability of tactical errors, and reduce power requirements for equivalent link performance while still maintaining good throughout low rejection rate. The use of error correction coding for communication links operating in a jamming environment affords the system two advantages. The most obvious advantage is that it allows the system to meet the required message error rate performance with less energy per bit when the main noise source is considered as additive Gaussian noise. The difference in the required values of EbNo with coding and EbNo without coding to meet the specificed error performance is known as coding gain. The second advantage of error correction coding is that it allows a system to obtain error rates that could never to achieved in an uncoded system.
