Problems solved by technology

Since the path resources of each user are discrete, the signal processing, data storage and access for each path are discrete, which will lead to low efficiency of data access, low efficiency of instructions, and lead to overall system efficiency. Low

example 1

[0043] Example 1: Assume that a certain user has 6 paths, the existing technology processes them sequentially according to the paths, and needs to execute 6 corresponding algorithm processing; while the embodiment of the present invention processes them sequentially according to Group, 6 paths occupy 2 Group resources, and need to execute Group 2 times Operation, because one 4-way parallel processing instruction can complete the algorithm processing of 4 paths in a Group, so the amount of computation of one Group operation instruction is equivalent to the amount of computation of one path in the prior art. In this case, the efficiency is increased by about 3 times.

example 2

[0044] Example 2: Assume that a certain user has 8 paths, the existing technology processes them sequentially according to the paths, and needs to perform 8 corresponding algorithm processing; while the embodiment of the present invention processes them sequentially according to Group, 8 paths occupy 2 Group resources, and need to execute Group 2 times Operation, the calculation amount of one Group operation instruction is equivalent to the calculation amount of one path in the prior art. In this case, the efficiency is increased by about 4 times.

example 3

[0045] Example 3: Assume that a certain user has 6 paths, and the data of each path is 16 bits. The prior art stores data according to paths, and needs to perform 6 corresponding accesses; while the embodiment of the present invention accesses data according to Groups, 6 paths occupy 2 For Group resources, each Group only needs to execute 2 32bit instructions to complete the corresponding access, and only needs to execute 4 corresponding accesses in total. In this case, the efficiency is increased by about 1.5 times.

[0046] Example 4: Assume that the user has 6 paths, and the data of each path is 32 bits. The existing technology stores data according to the path, and needs to perform 6 corresponding accesses; while the embodiment of the present invention accesses data according to Group, 6 paths occupy 2 Goups For resources, each Group only needs to execute the 4*32bit vector instruction once to complete the corresponding access, and only needs to execute the corresponding a...

Abstract

The invention discloses a multipath signal processing method which comprises the following steps: receiving multipath signals sent by a user; allocating multiple group resources to the user according to the number of the path signals of the multipath signals, wherein each group resource comprises a set number of continuous path resources; and carrying out parallel processing on the path signals corresponding to each group resource. The embodiment of the invention also provides a corresponding uplink receiver and a base station. In the technical scheme of the invention, the signals are processed based on group and each group comprises the multiple paths, so multiple path signals corresponding to each group resource are concentratedly processed, thus the processing efficiency of the multipath signals can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multipath signal processing method, an uplink receiver and a base station. Background technique [0002] In a Wideband Code Division Multiple Access (WCDMA) system, an uplink receiver of a base station (NodeB) generally adopts a RAKE combination method for processing baseband physical layer signals. Please refer to figure 1 , the RAKE combination method includes: performing multipath search on the received baseband input signal from the user, separating the multipath (Finger) signal, and obtaining the multipath time delay of each path signal; mediating each path signal respectively Processing, the mediation processing includes code correlation, channel estimation and delay equalization, etc., to obtain the output signal of each path; and then perform RAKE combination on the output signals of multiple paths to obtain the final received signal. It can be seen that the pr...
