Apparatus and Method for Inter-Carrier Interference Cancellation |
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.
