BER Performance of Different Modulation Schemes for MIMO Systems


Madan Lal, Hamneet Arora


Vol. 11  No. 3  pp. 69-72


In this paper we have discussed Multiple Input Multiple Output(MIMO) in Wireless medium by using Spatial Multiplexing technique for the calculation of the Bit Error Rate (BER). MIMO improve the throughput in wireless medium. It achieves a higher spectral efficiency. Spatial multiplexing increases the capacity and link reliability of the MIMO systems. The BER performance of BPSK, QPSK and QAM in MIMO systems in Rayleigh multipath channel is analyzed. V-Blast is used as a detection technique. A comparision of these modulations is also done in Rayleigh fading channel.
