Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] figure 1 The composition diagram of the diversity receiver provided by the embodiment of the present invention, such as figure 1 As shown, it mainly includes: RF receiving circuit, analog baseband circuit (ABB), digital baseband circuit (DBB) 13, terminal status / service type query circuit 14, diversity reception switching judgment circuit 15 and control circuit 16. In this embodiment, only two antennas are given. In practical applications, the diversity receiver may also have more than three antennas. At this time, the composition of the diversity receiver is based on figure 1 It can be obtained by simply expanding the number of RF receiving circuits and analog baseband circuits, and will not be drawn one by one here. in:

[0063] RF receiving circuit: Amplify, filter, and down-convert the signal from the antenna, and output...

Abstract

The invention discloses a diversity reception, switch and control method and a diversity reception machine. The method comprises the following steps of: detecting the business type at a terminal, and carrying out diversity reception, switch and control for the terminal according to the business type at the terminal. Through the method, the diversity reception, switch and control for the terminal can be carried out according to the business type at the terminal. Moreover, under the premise that the business quality of the diversity reception machine is increased, not only can the diversity reception gain be fully utilized but also the terminal power consumption can be reduced, and therefore the terminal can work for a longer time. The method is not confined to a specific communication system and can be suitable for any terminal using diversity reception.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a diversity receiving switching control method and a diversity receiver. Background technique [0002] Fading effect is one of the main factors affecting the quality of wireless communication. In order to counteract the influence of fading on reception, two or more receiving antennas can be used to receive signals carrying the same message with little correlation with each other on each branch, and then combine the signals of each branch through combining technology output, thereby greatly reducing the influence of fading on the system at the receiving terminal and improving the receiving sensitivity. [0003] Space diversity reception needs to use more than 2 receiving links in the receiver while improving the receiving performance. Therefore, compared with a single antenna, the power consumption of the radio frequency circuit and the digital receiving circuit wi...
