    摘要: A wireless communication receiver includes a first signal processing block, a second signal processing block, and a de-interleaver. The first signal processing block is configured for receiving a wireless communication signal and processing the wireless communication signal to generate a first output. The de-interleaver is coupled between the first signal processing block and the second signal processing block, and includes a plurality of branches implemented for de-interleaving the first output to generate a second output. The de-interleaver starts outputting the second output to the second signal processing block for further signal processing before all buffers included in the branches are full, and informs the second signal processing block of data derived from one or more unfull buffers included in the branches.

    摘要: 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.

    摘要: A multi-path receiving system is provided. The multi-path receiving system includes a multi-path analyzer, a channel estimator and an equalizer. The multi-path analyzer analyzes a channel impulse response (CIR) of the multi-path channel from the received stream. The channel estimator calculates a channel estimation result from the received stream. The channel estimator comprises a frequency domain interpolation filter performing channel estimation. The frequency domain interpolation filter consumes an amount of power according to the CIR result output from the multi-path analyzer. The equalizer equalizes the received stream based on the channel estimation result.
