摘要： The present invention provides an antenna-array-based multiple-input multiple-output orthogonal-frequency-division-multiplexing (MIMO-OFDM) system and a pre-coding and feedback method used in the same. The present invention uses QR decompositions of the MIMO channel matrixes to parameterize the channel state information (CSI) of every OFDM frequency band. In addition, the present invention feeds back the information related to θ and φ in the Givens rotation matrixes of the partial frequency bands and then uses an interpolation method to generate θ and φ in the Givens rotation matrixes of all the frequency bands, which further is able to represent the CSI of all the frequency bands. In this way, the present invention has advantages of low complexity and low feedback rate requirement.

摘要： A channel parameter estimation method adapted to a wireless communication system is proposed. The wireless communication system includes a transmitter and a receiver. The proposed method includes following steps. The transmitter transmits a plurality of pilot signals to the receiver by using one of a plurality of preconfigured sparse random pilot patterns. The receiver receives the pilot signals, performs a channel parameter estimation on the pilot signals by using a compressive sensing algorithm to obtain a multipath channel number, and selects a pilot pattern for a next cycle among the preconfigured sparse random pilot patterns according to the multipath channel number and a current pilot number. Additionally, the receiver transmits feedback information associated with the selected pilot pattern to the transmitter.

摘要： A beam-former searching method and a central unit using the method are proposed. The proposed method is adapted for a coordinated multi-point transmission for macro-diversity or an interference alignment scheme, and includes following steps. A metaheuristic algorithm is used to search for precoders and postcoders respectively for B of collaborative transmitters and U of receivers, where U=B for interference alignment and U=1 for coordinated multi-point transmission for macro-diversity. Memory is initialized by generating solution vectors randomly Utility functions is computed respectively for the generated solution vectors and the generated solution vectors are sorted respectively according to the computed utility functions. A new solution vector is improvised iteratively until the number of iterations reaches a pre-configured algorithm termination upper limit. In addition, a solution vector is selected as an output according to the computed utility functions.
