- Abstract
Use of space-time line coding (STLC) and block coding (STBC) are of interest in wireless sensor networks (WSN). They all bring the most incredible diversity to the information system. This gain can be proportional to the product of the number of transmit and receive antennas. However, one issue that needs attention is the bit error ratio (BER). When channel state information (CSI) is known at the transmitter, it uses STLC for the downlink and STBC for the uplink, which can improve BER. In cases where CSI is known to both the transmitter and receiver, these encoding techniques, when combined with beamforming, will result in even lower bit rates. This paper focuses on this combination to improve BER in multipath environments.
