High Data Rate MIMO-OFDM System using V-BLAST Architecture
نویسنده
چکیده
High date rate wireless systems with very small symbol periods usually face unacceptable Inter-Symbol Interference (ISI) originated from multipath propagation and their inherent delay spread. Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier-based technique for mitigating ISI to improve capacity in the wireless system with spectral efficiency (bps/Hz). On the other hand, Multiple -Input Multiple-Output (MIMO) systems have rising attention of the wireless academic community and industry because their promise to increase capacity and performance with acceptable BER proportionally with the number of antennas. Thus we have obtained better bit error rate using V-BLAST technique.
