Abstract:

An investigation was made comparing the system performance improvment in a coded correlation communication system under heavy jamming environment for the following forms of message encoder and decoder 1 simple reduction of the transmission rate, 2 simple repetition of the same symbol, and 3 application of error-correcting codes. The error-correcting codes were found to perform uniformly better than the other two schemes. For a rate reduction of 10, the antijamming margin gain achieved by the use of error-correcting codes is about 2 to 3db better than that obtained simply by reducing the transmission rate the symbol repetition scheme is definitely not to be recommended under the same condition. A physical interpretation of the different behavior is also included. Author
