Space-Time-Frequency Coded OFDM Over Frequency-Selective Fading Channels
Overview The major driver for broadband wireless communications has been reliable high-data-rate services (e.g., real-time multimedia services). This, together with the scarcity of bandwidth resources, motivate research toward developing efficient coding and modulation schemes that improve the quality and bandwidth efficiency of wireless systems. In wireless links, multipath fading causes performance degradation and constitutes the bottleneck for increasing data rates. Traditionally, the most popular technique to combat fading has been the exploitation of diversity. This paper proposes novel space-time-frequency (STF) coding for multiantenna orthogonal frequency-division multiplexing (OFDM) transmissions over frequency-selective Rayleigh fading channels.
