Problems solved by technology

[0016] To sum up, neither of the traditional two RAKE receiver devices can meet the WCDMA R6 protocol and its subsequent protocol requirements, and a new RAKE must be adopted, which not only meets the time limit requirements, but also does not require too much storage resources.

Embodiment Construction

[0051] From the traditional RAKE receiver shown in Figure 1 and Figure 2, it can be seen that the main advantage of the synchronous demodulation RAKE receiver device is to meet the processing time requirements of the uplink high-speed service data channel in the R6 protocol of 3GPP and subsequent protocols. The main advantage of the delayed demodulation mode RAKE receiver device is to make up for the shortcomings of the large amount of transmission and storage data caused by the synchronous demodulation mode.

[0052] However, the processing time of the RAKE receiver device in the delay demodulation mode cannot meet the processing time requirements of the uplink high-speed service data channel in the R6 protocol of 3GPP and subsequent protocols, so it is necessary to reduce the processing time of the RAKE receiver device in the delay demodulation mode. Since the delay demodulation mode RAKE receiver device stores the antenna data of one frame time for the corresponding DPDCH to...

Abstract

The invention is concerned with the mixing operation RAKE receiver of broad band code division multiple access system (CDMA) and the method. In contrast with the current time delay demodulation RAKE receiver, it adds the antenna data speed reading / repeat module, the multi-pathway parameter control module. It is that the antenna data speed reading / repeat module speeds up the reading of the antenna read-write control module or repeat reading of the deferred antenna data of the data memorizer, generates the final control channel data and the data channel information after processed by the after-progress module separately, according to the multi-pathway parameter of the multi-pathway parameter control module and the deferred antenna data of the multi-pathway demodulation module. It fulfills the processing time demand of the high speed operation data channel of WCDMA.

Description

technical field [0001] The present invention relates to wideband code division multiple access system (WCDMA, Wideband-Code Division Multiple Access) base station baseband processing technology, relate in particular to a kind of E-DPCH (uplink enhanced dedicated physical channel, Enhanced DedicatedPhysical Channel, Enhanced DedicatedPhysical Channel ) and a base station uplink receiving device and method for R99 services. Background technique [0002] In the WCDMA wireless communication system, due to the complex and harsh space wireless transmission environment, a RAKE receiver device is usually used for reception, and the wireless signal is recovered by demodulating multiple multipaths and then performing maximum ratio combining. [0003] The RAKE receiver of the traditional base station baseband processor usually has the following two implementation methods in the WCDMA system: [0004] (1) One is a simultaneous demodulation mode of a dedicated physical control channel (...
