Multipath fading compensation technique using pilot and data bearing symbols in mobile radio channels

Conference Theme: The Global BridgeThe paper studies techniques for transmitting a 16-ary quadrature-amplitude modulated (16QAM) signal in different mobile radio environments. Conventional multipath fading compensation techniques using only the pilot symbols, incorporated with zeroth-order and first-order prediction methods, are studied. Novel techniques making use both the pilot symbols and the data symbols, together with the improved zeroth-order and first-order prediction methods, are proposed. A series of intensive Monte Carlo simulations has been carried out on these techniques and the results have shown that, at high signal-to-noise ratios (SNRs), the bit-error rate (BER) performance can be reduced by a factor of about 46 and 2 using the improved zeroth-order and first-order prediction respectively, relative to those obtained using the pilot symbols only.published_or_final_versionThe 1994 IEEE Global Telecommunications Conference (GLOBECOM '94), San Francisco, CA., 28 November-2 December 1994.
