Abstract
The invention relates to an optimization method of dual-mode receiver applied in an automotive wireless digital TV receiver. It detects signal quality received by two receivers, and selects one to be a main receiver and the other to be an auxiliary receiver. Then, it judges whether the channel parameter of channel signal received by the receivers is pre-stored. If yes, it directly takes the pre-stored channel parameter; otherwise, it proceeds to scan channel parameter to search for channel parameter of the l channel signal. After that, record the channel parameter, and then demodulate the channel signal according to the channel parameter to obtain a transmitting data stream separately. Finally, the invention performs synchronous calculations for the transmitting data stream to output a synchronous and combined data stream. Therefore, it can effectively increase receiving performance and maximize benefits of two receivers.
