Embodiment Construction

[0065] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0066] An example of a receiver structure combining equalization and joint detection according to the present invention is figure 1 shown. The receiver includes a joint detection receiver and an equalization receiver for receiving input signals respectively, a controller for controlling the work of the joint detection receiver and equalization receiver and controlling the selector for selection, and a demodulator for demodulating the output signal of the selector . When the spreading factor is 1, the equalization receiver is activated, and the signal for eliminating inter-symbol interference is output through equalization processing; when the spreading factor is greater than 1, the joint detection receiver is activated, and the signal for eliminating interference is output through joint detection processing; Select an output from the equalization receiver or the jo...

Abstract

This invention relates to receiver combined with equilibrium and integration technique, which comprises the following parts: equilibrium receiver to receive the expansion factors activated and to process the interference signals through equilibrium technique; integration test receiver to receive the data expansion factors activated and process the multiple-address interference between signals though integration technique; selector to selectively output; controller to activate the said receiver and test receiver according to senior expansion factors and to control the output of the receivers.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a receiver and a receiving method of the third generation mobile communication system TD-SCDMA (Time Division Synchronous Code Division Multiple Access) system. Background technique [0002] With the increasing demand for high-speed data transmission in future multimedia services, wireless data services will increase sharply, which requires that the third-generation mobile communication system must have some characteristics suitable for transmitting data services, such as high data volume, high burst, high reliability etc. For the TD-SCDMA system, one of the third-generation mobile communication standards, it can provide not only high-quality low-speed voice services, but also high-quality high-speed data transmission services for various users with different communication needs. The usual TD-SCDMA system supports variable spreading factor. When the spreading fact...
