Abstract
A modified self-normalizing combiner is presented and its performance is analyzed under partial-band jamming. This is compared with other non-linear combining schemes. Continuing on our previous work, the throughput performance of a coded Fast Frequency Hopped M-ary Frequency Shift Keying (FFH/MFSK) system with a fixed hop rate is evaluated using the cutoff rate argument. The analysis upperbounds the gains which can be realized using coding for various system parameters. As a prelude to the study of coding for Slow Frequency Hopped Differential Phase Shift Keying (SFH/DPSK), we derive the probability distribution of DPSK in tone interference. A comparison of two powerful DSP integrated circuit processors for implementation of a decoder for the (127,99) BCH code is presented as a Appendix. TRUNCATED
