Abstract

The invention relates to a wireless receiver and method. The method comprises the following steps: setting a plurality of favorable channels to be scanned; periodically scanning the favorable channels and obtaining signal strength of each favorable channel and the signal strength difference between the present scanning period and the last scanning period; calculating the evaluation value for each favorable channel according to the signal strength of each channel and the signal strength difference between the present scanning period and the last scanning period; when the evaluation value of the present listening channel is less than a first given value, selecting one candidate channel as a replacing listening channel according to the evaluation value; and receiving the wireless signal of the listening channel. When the received wireless signal weakens, the invention can automatically select the listening channel, and ensure the quality of the received wireless signal.

Description

【Technical field】 [0001] The invention relates to a radio receiving device and method, in particular to a radio receiving device and method capable of automatically selecting channels. 【Background technique】 [0002] At present, radio receiving devices are widely received by people, and people can use radio receiving devices to listen to audio, which brings leisure and relaxation to people's lives. However, due to the limitations of the radio receiving device itself, people are limited when listening to audio. For example, when a vehicle equipped with a radio receiving device travels from one place to another, the signal of the originally listened-to channel becomes weaker, making the effect of the radio signal it receives worse. [0003] In the traditional method, the user needs to search continuously in the broadcasting frequency range to obtain a suitable frequency, and this method requires manual frequency adjustment, which is very cumbersome. 【Content of invention】 ...
