Abstract

A new power and bandwidth efficient modem technique, correlative encoded FSK (CEFSK), is proposed for use in RF home networking system. Power spectral densities (PSD) and BER performance of CEFSK are analyzed and compared with those of GFSK via computer simulation. A new fractional multi-bit differential detection (FMDD) technique is also proposed in order to improve the BER performance of CEFSK. Our simulation results show that CEFSK has a spectral efficiency comparable to GFSK, and that BER performance of CEFSK using 5-branch FMDD technique outperforms that of GFSK by 2.0 dB at a BER=1 × 10^-4 in AWGN and multipath fading channels.
