Description

technical field [0001] The present invention relates to the communication field, in particular, to a baseband processing system and method. Background technique [0002] Orthogonal Frequency Division Multiplexing (OFDM for short) scheme or Orthogonal Frequency Division Multiplexing Access (OFDMA for short) has been widely used. In OFDM technology, multiple independent subcarriers are used to increase efficiency. The process of modulating / demodulating the plurality of mutually opposite subcarriers at the sending / receiving end is similar to Inverse Discrete Fourier Transform (Inverse Discrete Fourier Transfer, referred to as IDFT) and Discrete Fourier Transform (DFT for short). ) execution process. Similarly, these subcarriers can also be constructed by means of Fast Fourier Transfer (FFT for short). [0003] OFDM technology is a multi-carrier transmission technology. Its main idea is to divide the total channel bandwidth into several orthogonal sub-carriers, convert high-s...
