Embodiment Construction

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0041] image 3 A flow chart showing a method for realizing demultiplexing of transmission channel data in the receiving direction in WCDMA according to an embodiment of the present invention, including the following steps:

[0042] Step S10, performing deinterleaving for the first time on the data obtained after decomposing the data in each radio frame of a transmission time interval frame into the transmission channel;

[0043] Step S20, deleting the discontinuous transmission bits of the data after the first deinterleaving for fixed position mapping;

[0044] Step S30, performing de-duplication rate matching on the data after the discontinuous transmission bit is deleted;

[0045] Step S40, perform wireless frame connection on the deduplication rate-matched data in the storage space.

[0046]In this embodiment, the de-repetitio...

Abstract

The invention provides a method and a device used for realizing demultiplexing of transmission signal-path data of the receiving direction in WCDMA. The method comprises the following steps: data obtained after the decomposition of the transmission signal path of the data in every wireless frame of a transmission time interval frame is firstly deinterlaced, discontinuously-sending bite deletion offixed-position mapping is carried out for the data deinterlaced for the first time; the match of repletion rate removal is carried out to the data subjected to the discontinuously-sending bite deletion; and wireless frame connection is carried out to the data subjected to the match of repletion rate removal in a storage space. The invention saves the cost of the demultiplexing of the transmissionsignal path.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for demultiplexing transmission channel data in the receiving direction in WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access). Background technique [0002] In the existing mobile communication technology, after the signal sent from the base station is combined by RAKE in the baseband of the mobile phone, the I and Q data of each physical channel are deinterleaved for the second time and all physical channel data Connection; secondly, perform variable position DTX (Discontinuous Transmission, discontinuous transmission) bit deletion on the physical channel data; then perform transmission channel decomposition on all data from the physical channel, and decompose the data of each wireless frame into eight transmission channels Middle; connect the data of all wireless frames in each TTI (Transmission Time Interval, transmissio...
