Multiple Beamforming With Perfect Coding
Perfect Space-Time Block Codes (PSTBCs) achieve full diversity, full rate, non-vanishing constant minimum determinant, uniform average transmitted energy per antenna, and good shaping. However, the high decoding complexity is a critical issue for practice. When the Channel State Information (CSI) is available at both the transmitter and the receiver, Singular Value Decomposition (SVD) is commonly applied for a Multiple-Input Multiple-Output (MIMO) system to enhance the throughput or the performance. In this paper, two novel techniques, Perfect Coded Multiple Beamforming (PCMB) and Bit-Interleaved Coded Multiple Beamforming with Perfect Coding (BICMBPC), are proposed, employing both PSTBCs and SVD with and without channel coding, respectively.
