    摘要: A method for co-channel interference suppression in Orthogonal Frequency Division Multiplexing (OFDM) systems with multiple receiving antennas is provided, wherein the co-channel interference (CCI) in different directions is suppressed by the spatial technique provided by the antenna arrays, and the interference to a desired carrier caused by other sub-carriers is also taken into consideration, that is, the interference of other sub-carriers is cancelled by means of a multistage interference cancellation, thereby the performance for interference suppression is improved.

    摘要: A wireless communication system, method for transmitting a frame, and computer program product thereof are provided. The system comprises a base station and a subscriber station. The frame comprises a MAP area and a user area. The MAP area comprises a broadcast test area. The method and the computer program product thereof operate: the base station initially transmitting a first burst in the user area by a first transmission module; determining whether the first burst that is transmitted by the first transmission module fits a special situation; and if yes, the base station transmitting test information in the broadcast test area by a second transmission module or asking the subscriber station to transmit data by a second transmission module.

    摘要: A wireless communication system, an apparatus, and a method for transmitting information to describe network topology of the wireless communication system in a mobile multi-hop relay standard are disclosed. The system can either be a two-hop relay station system or a multi-hop relay station system. The apparatus can use a CDMA ranging code set to transmit information and manage other apparatuses of the wireless communication system under a mobile multi-hop relay standard. The CDMA ranging code set comprises a mobile station (MS) code set and a relay station (RS) code set. The MS code set is used to transmit information from the MS to the base station (BS). Likewise, the RS code set is used to transmit information from the RS and the BS.
