A method of reducing memory effect of a power amplifier (PA), for a look-up table (LUT) based memory digital pre-distortion (DPD) circuit of an electronic device is disclosed. The method comprises generating a pre-distorted signal according to a LUT including parameters of an input signal amplitude and an input signal delay associated with a bandwidth of a signal inputted to the memory DPD circuit, and outputting the pre-distorted signal to the PA for improving the nonlinearity of the PA.

Method of reducing memory effect of power amplifier

A wireless communication receiver includes a first signal processing block, a phase noise compensation apparatus, and a second signal processing block. The first signal processing block is arranged for generating a first processed output by processing a reception signal, wherein the first signal processing block includes a channel estimation unit arranged for performing channel estimation. The phase noise compensation apparatus is arranged for receiving the first processed output and generating a second processed output by performing phase noise compensation according to the received first processed output. The second signal processing block is arranged for receiving the second processed output and processing the received second processed output.
