Recent research addresses towards multitransmit, multireceive antenna scheme to improve the performance in high data rate wireless communications.

Abstract
Recent research addresses towards multitransmit, multireceive antenna scheme to improve the performance in high data rate wireless communications. In this paper, we examine the combination of Bell-Labs layered space time (BLAST) wireless architecture and the iterative demapping and decoding, the turbo decoding principle. This structure, known as T-BLAST, was evaluated according to the IEEE 802.11b standard requirements for wireless LAN. The paper considers the design of the modified 'soft' Complementary Code Keying (CCK) modulation/demodulation scheme more suitable for the iterative interference cancellation receiver and shows the performance evaluation of this T-BLAST and SOFT CCK MODEM in the specific environment of the IEEE 802.11b standard. The paper also presents the throughput versus distance to receiver varying the number of transmit antennas in the indoor environment.File | Dimensione | Formato | |
