Abstract
In MIMO systems the interference from the same cell transmit (TX) antennas causes severe interference. Moreover, if the channel is frequency selective, also inter-chip interference is present. Canceling both inter-antenna and inter-chip interference is a challenging task, especially when the same codes are reused across the TX antennas. In this paper we propose a hybrid receiver combining minimum mean square error (MMSE) equalizer and chip level inter-antenna interference canceler. The performance is studied via simulations carried out in High Speed Downlink Packet Access (HSDPA) system with ITU channel.Keywords
