%X The block-modulated based OFDM algorithm is presented in MIMO-OFDM system to reduce the cost that is taken up by the Cyclic Prefix (CP). At each transmitter antenna, P OFDM data blocks are modulated jointly and framed together to use one single CP, and after the received frame at each receiver antenna is decomposed, P received blocks are obtained without inter-block interference where the pth block is equal to the sum of the pth OFDM data block in each transmitter passing through the MIMO channel. While the transmission mode and performance of the scheme proposed are equivalent to that of conventional MIMO-OFDM system, the band efficiency is improved dramatically.
