Abstract

We consider a multiple-access frequency-hopped system employing antenna diversity and error correction coding. A construction based on orthogonal Latin squares is used for the hopping patterns to improve code performance in the presence of interference. The measures of interest are the system performance, delay and decoder complexity, providing a basis for comparing BCH, Reed-Solomon (RS), and convolutional codes. It is shown that when binary non-coherent FSK modulation and hard decision detection are used, the BCH, RS, and convolutional codes that can meet the delay and bandwidth constraints have similar performance and comparable complexity. Soft decision decoding for the convolutional code and error-and-erasure correction decoding for the RS code are investigated in terms of the performance-complexity trade-offs for different decoding metrics. It is shown that improvement over hard decision decoding is significant when the right decoding metric is selected.
