Research on Channel Capacity of a MIMO Transform Domain Communication System

With the excellent ability of anti-interference, the conventional Transform Domain Communication System (TDCS) is conditioned in extensive application for the low data rates between the transmitter and the receiver. This paper presents a Multiple-input Multiple-output Transform Domain Communication System (MIMO-TDCS) by adding MIMO technique and V-BLAST receiver architecture to TDCS, by which improved the channel capacity. The paper introduces the scheme and function model of MIMO-TDCS as well, and analyzes its channel capacity mostly. The analysis shows that the channel capacity of the proposed MIMO-TDCS is higher than that of conventional system. Our simulation results also indicate that the proposed system is a kind of available communication technique which has interference mitigation ability in a certain extent.
