at a receiver, a phase rotation of the received data stream is determined to remove a residual frequency error or to estimate the phase noise.
在接收机处,确定所接收的数据流的相位旋转以去除残留频 率误差或者估算相位噪声。
this algorithm combines the block pilot-aided ls channel estimation algorithm with a phase tracking algorithm, which can compensate the phase rotation caused by the residual carrier frequency offset.
