Embodiment 1

[0020] figure 1 It is a schematic structural diagram of a wireless receiver embodiment of the present invention, such as figure 1 As shown, the wireless receiver of this embodiment may include an antenna 11, an intermediate radio frequency module 12, a baseband antenna data module 13, a user antenna data separation module 14, and a Multiple Input Multiple Output (Multiple Input Multiple Output, referred to as: MIMO) decoding module 15. Channel decoding module 16 and virtual user antenna data separation module 17.

[0021] In the present embodiment, antenna 11 can receive test data, and this test data can be set as the data of a user when carrying out the channel test of wireless receiver; And, one antenna 11 corresponds to a channel, and the test data that it receives can enter The test data is transmitted in a corresponding channel, and the test data may be referred to as channel data. The middle radio frequency module 12 is connected to the antenna 11, and can perform filt...

Embodiment 2

[0032] figure 2 It is a schematic flow chart of Embodiment 1 of the wireless receiver channel test method of the present invention. The wireless receiver channel test method of this embodiment can be executed by the wireless receiver described in any embodiment of the present invention. Such as figure 2 As shown, the method may include the following steps:

[0033] Step 201, the wireless receiver groups the channel data of the test channel according to the channel test mode information; the channel test mode information is single channel test or combined channel test;

[0034] For example, the single-channel test in the channel test mode information refers to the need to test the channel indicators (such as receiving sensitivity, demodulation threshold, etc.) of each channel separately; the joint channel test refers to the need to test the combined Channel index, to verify the signal reception performance of different channel combinations, wherein, the test of this joint c...

Embodiment 3

[0040] image 3 It is a schematic flow chart of Embodiment 2 of the wireless receiver channel test method of the present invention. The wireless receiver channel test method of this embodiment can be executed by the wireless receiver described in any embodiment of the present invention. Below to figure 1 wireless receiver shown as an example, combined with image 3 As shown, the method may include the following steps:

[0041] Step 301, the middle radio frequency module processes the test data received by the antenna;

[0042] For example, the mid-radio frequency module can filter and reduce the frequency of the test data, and convert the high-frequency test data received by the antenna into a time-domain signal.

[0043] Step 302, the baseband antenna data module further processes the data processed by the middle radio frequency module;

[0044] For example, the baseband antenna data module can further convert the test data into a baseband signal, at this time, it can be ...

Abstract

The present invention provides a radio receiver and a channel test method thereof, wherein, the method includes dividing channel data of multiple test channels into groups, according to channel test mode information which indicates a single channel test including testing the multiple test channels respectively or a joint channel test including testing multiple groups of the multiple test channels respectively; and processing each group of channel data individually, and obtaining test indexes of test channels corresponding to each group of channel data respectively. The test indexes of test channels corresponding to each group of channel data are obtained respectively in the present invention, which improves the efficiency of the channel test of the radio receiver.

Description

technical field [0001] The invention relates to communication technology, in particular to a wireless receiver and a channel testing method thereof. Background technique [0002] The wireless receivers used in modern wireless communication systems usually need to pass the channel index test before shipment in order to ensure the quality. [0003] The current channel index test of multi-antenna receivers generally requires multi-channel joint test or single-channel test. However, whether it is a single-channel test or a multi-channel joint test, only one test index can be obtained for each test. For example, for an 8-channel wireless receiver, when it is necessary to perform a single-channel test on each of the N channels, N channels are required to be tested cyclically, and only one channel is activated at a time, that is, each test can only get a single channel test Indicators; when it is necessary to test the combination of two channels in the 8 channels, such as testing...
