Problems solved by technology

Therefore, when the blocking interference signal is small or does not exist in the actual environment, the traditional receiver still works in the working mode where there is a large blocking interference signal, and its system configuration requirements are much higher than those required for the actual blocking interference signal. The minimum configuration required, that is, there is a system margin. Although the system can work, it increases the power consumption of the system and wastes system resources.

specific Embodiment

[0078] (1) The receiver configuration is adjusted in the pilot signal part, based on the strength of the pilot signal. Once the jamming signal is detected, the receiver is quickly adjusted to a higher power consumption mode to deal with the impact of the jamming signal, such as Figure 6 As shown in (a): in Figure 6 In (a), the system configuration adjuster usually adjusts the system configuration in the preamble area. When the blocking interference signal detector detects blocking interference in the data signal area, the system configuration adjuster immediately adjusts the system configuration in the data area; Figure 6 In (b), the system configuration adjuster only adjusts the system configuration in the leading signal area, and reserves a certain system margin. When the blocking interference signal detector detects blocking interference in the data signal area, the system configuration adjuster does not need to immediately adjust the system configuration, and the data...

Abstract

The present invention relates to a low power consumption receiver which can dynamically detect the blocking interference signal and belongs to the technical field of wireless communication. The receiver comprises the following components: a radio frequency amplifier, a frequency synthesizer, a first frequency mixer, a low-pass filter, a variable gain amplifier and an analog-digital converter which are connected in sequence. The receiver also comprises a blocking interference signal detector and a system configuration regulator connected with the detector. The input end of the blocking interference signal detector can be connected with the output end of the analog-digital converter, and can be connected with the input ends and output ends of the low-pass filter and variable gain amplifier at the same time. The output end of the system configuration regulator is connected with at least one device in all devices respectively, or is connected with a plurality of receiving chains which arecomposed of the devices through an N-route multiplexer. The receiver presented by the invention can automatically detect the strength of the blocking interference signal and regulates the system configuration correspondingly. The receiver is leaded to work in different working modes in order to adapt different working environments.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a structural design of a low-power wireless receiver capable of dynamically detecting blocking interference signals. Background technique [0002] In an open wireless environment, the signal received by the receiver is composed of the expected signal (referred to as the target signal in the present invention), interference signal and noise signal. In the present invention, the target signal is active, and the power generated by the actual target transmitter is relatively large. The interference signal is also active, so the power of the interference signal is relatively large. All transmitters working in the same frequency band or adjacent frequency bands) directly or indirectly. The noise signal is passive and consists of electromagnetic background noise and thermal noise. Generally speaking, compared with the interference signal, the power of the noise signal ...
