MIMO (Multiple Input Multiple Output)-OFDM (Orthogonal Frequency Division Multiplexing)technique is most attractive techniques in wireless communication system and it is very popular for high data rate capacity and against multipath fading.This paper presents performance analysis and a comparative study of OSTBC (Orthogonal Space Time Block Code) over Rayleigh fading channel for MISO (Multiple Input Single Output) defined that the transmitter has multiple antennas at the same time the receiver has one antenna and MIMO (Multiple Input Multiple Output) shows that the both the transmitter and receiver have multiple antennas.In this paper we propose QPSK (Quadrature Phase Shift Key), 16-QAM (Quadrature Amplitude Modulator) schemes and also observe that the performance of PAPR (peak power-to-average ratio), BER (bit error rate) in MIMO and MISO.
