Recent developments in wireless communications have shown that with the use of multiple antenna elements at both transmitter and the receiver, it is possible to substantially increase the capacity of a wireless communication system without increase in the transmit power and bandwidth. The current work is proposed to design an efficient fast fading channel estimation scheme for orthogonal frequency division multiplexing (OFDM) using 8x8 multiple input multiple output (MIMO) antennas. The current scenario describes about reduction in PAPR using Spatial Multiplexing (SM). The MIMO-OFDM system data rates are supported by 4G wireless networks. The use of PTS technique with QPSK modulation comprising of 1024 subcarriers resulting in reduction of PAPR up to 2. 6dB is reported. The current work using similar parameters depicts the reduction in PAPR of 3. 6 dB against 2. 6 dB.
