Abstract

This paper evaluates a parallel blind demodulator combined with a Reed-Solomon (RS) decoder in the presence of intersymbol interference (ISI) by means of hardware experiments. Our target systems are point to multi-point (P-MP) communication systems for business use, of which bit rates in the air are 9.6 kbit/s. In such narrow frequency band systems, fast time-varying fading is a serious problem. The implemented parallel blind demodulator employs adaptive maximum-likelihood sequence estimation with per-survivor processing (PSP-MLSE), and the RS code is used for a forward error correction (FEC) code. Finally, experimental results confirm that the parallel blind demodulator combined with the RS decoder achieves excellent BER performance
