- W2390340156 abstract "In order to obtain maximum coding gain and full diversity gain in space,time and frequency for MIMO-OFDM systems,an improved rate-one space-time-frequency code is presented.The data streams are first rotated by an algebraic rotation matrix,and then designed orthogonally every two antennas in two OFDM blocks.Finally,the lower complexity sphere-decoding algorithm is used to perform the maximum-likelihood decoding algorithm after linear combination and whitened processing.Some code with 2×2 system and 4×1 system are simulated,the results show that the improved space-time-frequency code has 0.5～0.6dB of gain over the existing space-frequency codes,so it has wide applications." @default.
