Abstract: First incoming data comprising at least one OFDM symbol is received (302). A plurality of timing relationships is determined and each of the plurality of timing relationships relates to an alignment window of a fast Fourier transform (FFT) (304). Each of the plurality of timing relationships is applied to the first incoming data (306) and a plurality of achievable interference metrics associated with the first incoming data is responsively determined (308). Each of the plurality of achievable interference metrics is associated with a selected one of the plurality of timing relationships. The preferred interference metric is chosen from amongst the plurality of achievable interference metrics.

Abstract: An interference contribution associated with a selected subcarrier of a plurality of subcarriers associated with a previously transmitted OFDM symbol or a current OFDM symbol is determined (300). A fast Fourier transform (FFT) output for the current OFDM symbol is also determined (304). The interference contribution is subtracted from the FFT output of the current OFDM symbol to form a modified FFT output (308).

Abstract translation: 确定与先前发送的OFDM符号或当前OFDM符号相关联的多个子载波中的选定副载波相关联的干扰贡献（300）。 还确定了用于当前OFDM符号的快速傅里叶变换（FFT）输出（304）。 从当前OFDM符号的FFT输出中减去干扰贡献以形成修正的FFT输出（308）。
