Performance of slow frequency-hopped TDMA with a hard limited receiver

This paper discusses the performance of a slow-frequency-hopped time-division multiple access (SFH-TDMA) technique, which can be considered as a "high-tier" extension of a low-complexity TDMA architecture optimized for low-power pedestrian applications. A hard-limited receiver is employed and a novel weighting factor for diversity combining is developed to achieve an effect similar to that of a maximal ratio combiner. Numerical performance results for frequency-selective fading channels over a range of fading rates were obtained through computer simulations.
