Abstract:
In this paper, reception for multi-stream Orthogonal Frequency Division Multiplexing (OFDM) transmission is analyzed. The system architecture employs Linear Dispersion Space-Time Block Codes (LD-STBC). In the transmitter, a part of spatial streams is Space Time Block Coded (STBC). The LD-STBC-VBLAST OFDM receiver is described and analyzed. The quality of reception for Wireless-LAN (WLAN) transmission with channel type E is investigated using a computer simulation. We present the simulation results for two models of OFDM receivers. Performance of VBLAST and LD-STBC-VBLAST receivers has been compared. The Bit Error Rate (BER) and Packet Error Rate (PER) have been determined for different numbers of spatial streams in use. The results illustrate that the LD-STBC-VBLAST OFDM receiver improves the transmission quality in WLAN scenario.
