Reverse link correlation filter in multi rate cdma wireless communication systems

(Code division multiple access) in a wireless system for providing single and coherent filtering core in CDMA. Providing different data rate the wireless system multiple channels. The channel in the wireless systems providing a accessing channel, and channel and traffic channels flow channel, the information (e.g. pilot or symbols data in the channels service flow channel or two with two at the same time) according to first-level (despread basic speed), a diode and third-level speed transmission. Data transmitting data rate of baffles external programmable processor, program for example for digital signal processor. The user is coded; for example PN (pseudo-random noise), code is added to the information according to the wireless channel system for. The is information modulated and a channel any one of speed transmission. Transmitting data in wireless system and coherently filter through (or orthogonal coding PN code, Walsh code) each stage delay time multiplyings is stickiness filtering core, according to despread basic rate (i.e. first-level speed) related. And associated related information demultiplexing and demodulation. Demodulation information according to first-level number of basic (despread) of the pneumoelectric integral multiple under efficiently obtaining diode and third-level thereof. One or more signal component (according to receiving power, signal-to-noise ratio or multi-path) and dipole chosen is one or window, so that the number of optimizing the information retrieval. The selecting number of the shaft according to the time of correcting pre-programming is realized. In addition, capable of providing and synthesize the multi-channel output from demodulation method for time diversity. The space diversity through providing multiple antenna and receivers are arranged at the base; and each receiving antenna and system of providing the single coherent filter structure is realized.
