Wireless communication receiver, a wireless communication receiving method and a television receiver

摘要

The present invention relates to a wireless communication receiver, wireless communication receiving method and television receiver. The wireless communication receiver has signal processing circuits including a first signal processing circuit and a second signal processing circuit, a data storage module, and a deinterleaver. The first signal processing circuit receives a wireless communication signal and then performs a first signal processing to generate a first output data according to the wireless communication signal. The deinterleaver stores the first output data into the data storage module, and retrieves a deinterleaved data corresponding to the first output signal from the data storage module. The second signal processing circuit performs a second signal processing to generate a second output data according to the deinterleaved data. The data storage module is shared by the deinterleaver and at least one of the signal processing circuits for data storage, thereby effectively reducing the production cost.
