    摘要: Provided is an apparatus and method for estimating an uplink frequency offset in a wireless communication system. In a receiving apparatus of a wireless communication system using a random access channel composed of two equivalent sequences, the apparatus includes a channel receiver which extracts samples corresponding to the two sequences from an input random access channel signal; a correlator which computes first and second correlation values by correlating preceding and trailing samples among the samples output from the channel receiver with a predetermined sequence; and a frequency offset estimator which estimates a frequency offset by using a ratio of the second correlation value to the first correlation value output from the correlator.

    摘要: A method and an apparatus operate multi-user Collaborative Spatial Multiplexing (CSM) in a wireless communication system. A Base Station (BS), performs uplink transmission scheduling on multiple Mobile Stations (MSs). Resources units, which have been allocated to multiple layers spatially discriminated by the uplink transmission scheduling, are permutated by applying different permutation schemes according to layers. Uplink data is received from the scheduled MSs through the permutated resource units. Each MS uses permutation schemes according to the layers allocated in a manner corresponding to the BS. Therefore, when the multi-user CSM is used, self-interferences or interferences between layers are averaged, thereby reducing variable widths of parameters of various kinds and improving the prediction property of a received SINR. As a result, a Packet Error Ratio (PER) performance is improved when data is actually transmitted.
