Abstract

In this paper a MIMO system with transmit and receive antenna and the channel model with two methods of pilot-aided (PA) schemes are considered. The first scheme is pilot insertion (PI) scheme, where pilots are time multiplexed with data and the second scheme pilot embedding (PE) scheme, where pilots are added and transmitted concurrently with data. The study shows that PI scheme is better than PE scheme. To obtain the capacity the maximum-likelihood channel estimation is used. Then the discrete and continuous capacity of a MIMO channel with imperfect channel estimates is evaluated.
