Abstract :
This paper is concerned with the problem of channel estimation and symbol detection in fast fading channels, which is one of the challenges faced by extending spatial multiplexing to mobile terminals. A method of resolving this problem is the use of pilot aided channel interpolation techniques which are common in single channel systems. We propose an iterative algorithm that substantially improves the performance of pilot aided MIMO channel interpolation systems by exploiting the time selectivity of the channel.
