In this paper, we proposed reliability and capacity enhancement methods for IEEE 802.15.3 HDR-WPAN (High Data Rate-Wireless Personal Area Network) system which is currently getting an interest in home network technology adopting a M IM O technique. We also analyzed performance o f the proposed system through a computer simulation. The HDR-WPAN system using V-BLAST algorithm, transmitting the different signal vector to each other¡¯s sub-channel, can get the transmission speed o f more than 110Mbps using two Tx/Rx antenna without bandwidth expansion in TCM-64QAM mode. Also the proposed system has reliability o f 10-4 at ¡ÌJ/A ^= 35dB under the Rayleigh fading channel in case o f two Tx/Rx antenna with M M SE algorithm. The HDR-WPAN system adopting V-BLAST method has its drawback which is very complicated to determine the decision-ordering at the receiver. But, the proposed system enhances the transmission capacity and reliability without extra bandwidth expansion by sending data streams to multiple antennas. |
