Abstract
A method of canceling co-channel interference of a signal received by a mobile station having at least two receiving antennas, in a cellular OFDMA-TDD communication network having a serving base station and at least one interfering base station. The signal is a result of a serving signal transmitted by the serving base station which is distorted by at least one interfering signal transmitted by the interfering base station. The serving signal is transmitted with a first modulation scheme and the interfering signal is transmitted with a second modulation scheme. The method includes: a channel estimation phase delivering channel estimations of the serving signal and the interfering signal; and a MIMO detecting phase, detecting symbols by using the channel estimations of the serving signal and the interfering signal. The MIMO detection phase is realized using a non-linear method which uses the first modulation scheme and the second modulation scheme.
