| Summary: | Over the past few decades, spread-spectrum communication systems have attracted considerable interests in both commercial and military applications. Under the conditions of intentional or unintentional interference, it is effective to use error-correcting codes to improve the performance of fast frequency-hopped (FFH) spread spectrum systems. This dissertation addresses the problem of combating interference in FFH spread spectrum communication link. The fast frequency-hopped spread spectrum systems employ the binary frequency-shift-keying (BFSK) modulation and non-coherent demodulation with a soft-decision linear-combining receiver and error-control coding. The interference consists of multi-tone jamming (MTJ) and additive white Gaussian noise (AWGN). The coding scheme applied to the spread spectrum system is the Reed-Solomon (RS) codes. The RS coded system performance with errors-only decoding is presented. |
