摘要： The present invention discloses a method and apparatus of IQ imbalance compensation for a receiver. The repetitive attribute of the preamble in a signal received by the receiver is used to estimate the IQ imbalance parameters. The data carried by the preamble repeats itself every N sampling intervals. A MSE equation is derived based on assuming the ratios between any two sampling points separated by N samples are identical, and the IQ imbalance parameters can be estimated by solving the MSE equation using the LS algorithm. Consequently, the IQ mismatch offset of the signal is compensated according to the estimated parameters.

摘要： A communication device including a receiving unit and a signal processing module having a simulation unit and a decision unit is provided. The receiving unit receives a first burst of a paging message provided from a base station. Base on a reference burst code and an estimated channel impulse response of the communication channel, the simulation unit generates a simulation burst. The decision unit then determines if the paging message is a dummy message in accordance with the first burst and the simulation burst. The decision unit requests the receiving unit to stop receiving the paging message once the paging message is determined to be a dummy message.
