WIRELESS COMMUNICATION UNIT AND METHOD FOR RECEIVING A WIRELESS SIGNAL
摘要
A wireless communication unit (100) comprises a receiver for receiving a wireless signal having signal-to-noise ratio (SNR) measurement logic (112) for measuring a SNR value of the received signal and signal processing logic (108) arranged to process the received wireless signal. The signal processing logic comprises demodulator logic (255) operably coupled to log likelihood ratio (LLR) logic (262) and decoding logic (265). A scaling factor (Q) is applied to the LLR logic (262) dependent upon the measured signal-to-noise ratio.
