Problems solved by technology

The disadvantage of this method is that in the compressed mode, the TFCI bits that are repeatedly sent beyond the first 30 bits are discarded and are not used. At the same time, the bit error rate of the TFCI demodulation result has not been effectively reduced.

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] In general, the principle of the present invention is to perform a weighted average of the quantized results of the two sections of TFCI bits that are repeatedly sent to obtain a processing gain, thereby improving the wireless performance of TFCI transmission and better resisting multipath fading The influence brought by TFCI decoding and demodulation, and make the non-systematic errors caused by random interference offset each other, and reduce the bit error rate of TFCI demodulation results. figure 1 A TFCI demodulation method in uplink compressed mode according to an embodiment of the present invention is shown, and the method is applied to a WCDMA system.

[0026] As shown in the figure, first at step 110, it is judged whether the received TFCI bits exc...

Abstract

This invention discloses a demodulation method for a transmission format and combination instruction under an up compressed mode to reduce the error bit rate of the TFCI demodulation result, in which, weighted average is done to two sections sent repeatedly in the TFCI bit to get the process gain.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for utilizing repeatedly transmitted TFCI bits in a wideband code division multiple access system under non-blind rate compression mode. Background technique [0002] The third generation mobile communication (The Third Generation, referred to as "3G") technology can better provide services for multimedia communication. The high-quality images and videos provided by this technology further enhance the communication capabilities between people, and greatly enhance the access capabilities of information and services on public and private networks. [0003] There are three main types of 3G core technologies: Wideband Code Division Multiple Access (WCDMA for short), Code Division Multiple Access 2000 (CDMA2000 for short), and Time Division Synchronous Code Division Multiple Access (CDMA2000 for short). Time Division Synchronous Code Division Multiple Access, referred to as...
