ABSTRACT:
An OFDM receiver is provided. The OFDM receiver comprises a Fourier transform (FFT) module, a storage device, an equalizer, and a diversity combiner module. The Fourier transform module transforms a time-domain symbol into an OFDM symbol. The storage device stores OFDM symbols. When operated in a single chip mode, the storage device stores more OFDM symbols outputted from FFT module than operated in a diversity mode. The equalizer retrieves the OFDM symbols from the storage device or the FFT module, estimates the channel frequency response of a transmission channel, and equalizes the OFDM symbol according to the channel frequency response. When operated in the diversity mode, the diversity combiner module receives the OFDM symbols and an alignment signal from a diversity OFDM receiver.
