Title:
METHOD AND DEVICE FOR REDUCING SIGNAL PROCESSING COMPLEXITY OF MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2006/105689
Kind Code:
A1
Abstract:
Method and device for reducing signal processing complexity of the mobile terminal are disclosed. According to the method, a channel compensator is set in the BS, the channel compensator convolution processes the downlink signal transmitted by the BS, and therefore, the distortion caused by the wireless channel are compensated, the parameters of the channel compensator are obtained based on the estimated channel parameters. According to the present invention, the downlink wireless signal will be pre-compensated, and the pre-compensation will be dynamically adaptively adjusted based on the feedback about the channel parameters given by the BS or the mobile, therefore, the mobile can receive signal without equalization or with reduced rank equalization. And then, the signal processing complexity of the mobile is reduced dramatically, especially for the high-ranking modulation mobile communication system, and at the same time, the processor resource of the mobile terminal is saved.
