摘要： A signal receiving method of a receiver includes following steps. Multiple time-domain received signals are transformed into multiple frequency-domain received signals, and channel response matrices corresponding to the frequency-domain received signals are estimated. The frequency-domain received signals are STBC decoded and multiple original combination signals are obtained based on the corresponding channel response matrices. The frequency-domain received signals are rearranged, and the rearranged frequency-domain received signals are STBC decoded and multiple rearrangement combination signals are obtained based on the corresponding channel response matrices. The original combination signals and the rearrangement combination signals are randomly chosen and summed to obtain multiple complex signals. The complex signal with minimum interference power is selected and then the selected signal is used to cancel interference and compensate the channel effect to obtain the detected data.

摘要： A method for inter-carrier interference cancellation is provided. A time-domain received signal is detected to obtain information of an inter-symbol interference free region. Multiple cyclic useful symbols are obtained from the time-domain received signal according to the information of the inter-symbol interference free region and a set of multi-step windowing coefficients is generated. Adjusted cyclic useful symbols are obtained by multiplying the cyclic useful symbols by the set of multi-step windowing coefficients, respectively, and then combined in a time domain to obtain a time-domain combination signal. The inter-carrier interference of each of sub-carriers of the time-domain combination signal is centralized on neighboring D sub-carriers. The time-domain combination signal is transformed into a frequency-domain received signal. The frequency-domain received signal and its corresponding channel response matrix are divided into overlapped signal blocks according to D. Successive inter-carrier interference cancellation is performed on each signal block in parallel to obtain estimation data.
