Scalable layered space-time codes for wireless communications: performance analysis and design criteria
نویسندگان
چکیده
− Dual antenna-array systems provide very high capacity compared to single antenna systems in a Rayleigh fading environment. If the transmitter does not have channel state information, to utilize this high capacity, space-time codes must be employed. The diagonally layered space-time (DLST) architecture is a structure that is capable of providing a high data rate for a low decoding complexity. We analyze the performance of DLST codes with a hard decision-feedback decoder and a soft decision-feedback decoder with iterative decoding. We analyze the error-probability performance and propose criteria for designing the constituent codes.

Layered Space-Time Codes for Wireless Communications Using Multiple Transmit Antennas
− Multiple-antenna systems provide very high capacity compared to single antenna systems in a Rayleigh fading environment. Space-time codes are channel codes designed to exploit this high capacity for multiple-antenna systems without requiring instantaneous channel knowledge at the transmitter. A practical concern for high data rate space-time codes is their decoding complexity. The decoding co...

متن کاملLayered space-time multiuser detection over wireless uplink systems
In this paper, we investigate the use of layered space-time, also known as Vertical-Bell Laboratories Layered Space-Time (V-BLAST) scheme, for multiuser detection in fading channels. The multiple transmit antennas in V-BLAST are treated as individual mobile station transmitters, while the base station consists of multiple receive antennas. In the proposed system, users are organized in groups a...
