Abstract
It is known that multi-antenna transmissions over frequency-selective channels can provide a diversity gain that is product of the number of transmit antennas, the receive antennas and the length of the channel impulse response. Liu, Xin and Giannakis have studied multi-antenna Orthogonal Frequency Division Multiplexing (OFDM) through frequency-selective Rayleigh-fading channels and have introduced the concept of Space-time Frequency (STF) coding to enable maximum diversity and high coding gains. It is known that under some conditions, an n-length cyclic code C over Fqm (n|qm - 1 and m les n) can have fullrank i.e Rankq(C) = m. Designs for space-time codes suitable for both quasi-static fading channels and block-fading channels have been derived from n length cyclic codes over Fqm. In this paper, we present a simplified design of STF codes using designs derived from cyclic codes to obtain Group space-time-frequency (GSTF) codes for frequency selective Rayleigh fading channels. These codes achieve maximum diversity gain.
