Abstract--Multiple beamforming is realized by singular value
decomposition of the channel matrix which is assumed to be
perfectly known to the transmitter as well as the receiver. Bit-
Interleaved Coded Multiple Beamforming (BICMB) is known to
have a diversity order bound related with the product of the
code rate and the number of parallel subchannels, losing the full
diversity order in some cases. Bit-Interleaved Coded Multiple
Beamforming with Constellation Precoding (BICMB-CP), on
the other hand, can achieve the full diversity order. However,
the decoding complexity of BICMB-CP is much higher than
