Embodiment Construction

[0036] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0037] This embodiment provides a multipath detection method, such as Figure 4 shown, including the following steps:

[0038] Step S402: Receive a multipath search task, wherein the multipath search task includes: indication information of hardware resources that the multipath search task is allowed to occupy in different lengths of time periods;

[0039] Step S404: Allocating hardware resources for the multipath search task;

[0040] Step S406: Perform multipath detection on the multipath search task according to the allocated hardware resources.

[0041] In the above preferred implementation manner, the multipath search task assigned to the hardware has pre-determined the hardware resources tha...

Abstract

The invention discloses a multipath detection method and an apparatus. The method comprises the following steps: a multipath search task is received, wherein the multipath search task contains indicator information of hardware resources which are allowed at time quantum of different lengths; hardware resources are allocated for the multipath search task; and multipath detection is carried out on the multipath search task according to the allocated hardware resources. By the method, the technical problem that hardware resources for multipath search cannot be effectively controlled in the prior art is solved, and time division multiplexing of hardware resources is realized. Thus, utilization rate of hardware resources in multipath detection is raised.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a multipath detection method and device. Background technique [0002] In wireless communication systems, due to the different propagation environments of signals, there will inevitably be multipath interference problems. For a Code Division Multiple Access (CDMA for short) system, the Orthogonal Variable Length Spread Spectrum (OVSF) used has good auto-correlation and cross-correlation properties. According to this property, when the propagation delay of two identical signals exceeds one chip, the multipath signal can be regarded as the result of repeated transmission of the same signal at different times, so the multipath signal can be easily detected. [0003] At the same time, since the multipath signals contain available information, the CDMA receiver can improve the signal-to-noise ratio of the received signal by combining these multipath signals. The RAKE receiver is a...
