AI Technical Summary

Problems solved by technology

The conventional detection algorithm does not use the known information of the target user perfectly, and cannot accurately detect the information of the shift training system of the system, so it is necessary to effectively use all possible information assigned to the target user by the system at this time

Embodiment Construction

[0057] The following pass figure 2 , to introduce specific embodiments of the present invention in detail, so as to further understand the content of the present invention.

[0058] Such as figure 2 As shown, the present invention provides a kind of method for shift sequence detection under the user-specified distribution mode in the time division synchronous code division multiple access receiving system, and it comprises the following steps:

[0059] Step 1, calculate average noise power and noise threshold, in order to calculate average noise power, and produce the detection threshold Thr of discontinuous reception DTX ;

[0060] Step 1.1, calculate the average noise power:

[0061] According to the noise position information calculated in the previous frame, calculate the average noise power P in this frame by calculating the average value of the noise power at the noise position moise :

[0062] P noise = ...

Abstract

Said invention provides shift sequential detection method of user appointed distribution mode. It includes calculating average noise power and noise threshold for calculating average noise and generating noise judging threshold, to proceed discontinuous transmission detect and system discontinuous transmission state detect, and outputting efficiency estimation window number. Said invented method accurately detect out other user's information through utilizing user's physical layer coded combination transmitting channel information.

Description

technical field [0001] The invention relates to a method and device for shift sequence detection in a user-specified allocation mode, in particular, relates to a fast shift sequence detection method in a TD-SCDMA (Time Division Synchronous Code Division Multiple Access) communication system in a user-specified allocation mode. A method and device for accurate shift sequence detection. Background technique [0002] In the receiving device of the TD-SCDMA system, the distribution method of the shift sequence in the whole system is specified by the system. According to the setting of the network layer, there are three ways to allocate the training sequence of the system, such as figure 1 Shown: default allocation mode (DEFAULT), public allocation mode (COMMON) and user-specified allocation mode (UESPECFIC), in the three different shift sequence allocation modes, the known information that the system can obtain is also different, so Subsequent detection algorithms will also va...
