Multiple Beamforming with Perfect Coding
Boyu Li, Student Member, IEEE, and Ender Ayanoglu, Fellow, IEEE
Abstract--Perfect Space-Time Block Codes (PSTBCs) achieve
full diversity, full rate, nonvanishing constant minimum de-
terminant, 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 Cod-
ing (BICMB-PC), are proposed, employing both PSTBCs and
SVD with and without channel coding, respectively. With CSI
at the transmitter (CSIT), the decoding complexity of PCMB is
substantially reduced compared to a MIMO system employing
PSTBC, providing a new prospect of CSIT. Especially, because of
the special property of the generation matrices, PCMB provides
