Abstract

Abstract: An STBC-QOTDM Multi-input Multi-output (MIMO) is proposed, in which the Quasi-orthogonal Time Division Multiplexed (QOTDM) sample sequences are Space Time Block Coded (STBC) before transmission. Based on the integral relationship between the modified Gaussian Q-function, the probability density function and the characteristic function of the channel, a closed form solution for symbol error probability (SEP) of STBC-QOTDM due to the sample errors over spatially uncorrelated fading channels is derived. And the performance of STBC-QOTDM is also given by Monte Carlo simulation.

Key words: QOTDM, STBC, MIMO, Gaussian Q-function
