Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0045] An embodiment of the present invention provides a multipath demodulation method, which is applied to a multipath demodulation device, and the device may be a base station in a WCDMA system.

[0046] Such as figure 1 As shown, the multipath demodulation device includes: a task scheduling module 11 and a multipath demodulation module 12 . Wherein, the task scheduling module 11 is used to configure the multipath demodulation task (hereinafter referred to as: task) configured by the external configuration processor 13, that is, the configured task is scheduled to the multipath demodulation module 12 according to the effective time of the task; The modulation module 12 is used to perform multipath demodulation on each task that has been dispatched, and send the demodulation...

Abstract

Disclosed in an embodiment of the present invention is a multi-path demodulation method. The method comprises: in a current symbol period, when an ith sub-period is reached, detecting whether a task linked-list corresponding to the ith sub-period is empty, wherein the task linked-list takes as task nodes those tasks already in effect of an ith sub-period in a symbol period before the current symbol period, and i is a positive integer; and if the task linked-list is a non-empty linked-list, respectively performing multi-path demodulation on tasks already in effect and corresponding to task nodes in the task linked-list. The embodiment of the present invention also discloses a multi-path demodulation device and computer storage medium.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a multipath demodulation method and device. Background technique [0002] In the Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system, due to the existence of obstacles, the wireless signal sent by the user equipment (UE, User Equipment) will be transmitted in a variety of different propagation paths such as direct, reflection and refraction. , form different multipath fading channels, and propagate to the receiver. The receiver realizes receiving user signals by demodulating different multipaths belonging to each user equipment and then combining the multipaths. [0003] In the disclosed existing multipath demodulation technology, at first, all multipath demodulation tasks configured by software (hereinafter referred to as: tasks) are stored in a first-in-first-out (FIFO, First Input First Output) memory, and then The tasks...
