Problems solved by technology

[0003] However, during the communication process between the signal transmitting end and the signal receiving end, due to the interference of different communication environments, the signal transmission quality also varies from time to time.
Directly using multi-antenna diversity to receive signals will increase the power consumption of the signal receiving end, and compared with single antenna for signal reception, diversity reception and combined signals will also affect signal processing efficiency

Abstract

The embodiment of the present application discloses a receiving mode selection method and device based on signal diversity receiving. In the technical solution provided by the embodiment of the present application, in the initial signal receiving mode, several signals are independently received through the main antenna, and the first signal quality parameter of the received signal is determined. When the first signal quality parameter is lower than the first signal quality parameter When the threshold is reached, the current signal receiving mode is switched to the diversity receiving mode, and the master antenna and several slave antennas perform diversity reception of signals, and combine the signals received by diversity to obtain a combined signal, and within the set first time period, continuously The set number of times detects that the first signal quality parameter of the signal received by the main antenna reaches the first signal quality parameter threshold, and restores the current signal receiving mode to the initial signal receiving mode. Using the above-mentioned technical means can guarantee the signal receiving performance of the system, optimize the energy consumption management of the system, and improve the signal processing efficiency.

Description

technical field [0001] The embodiments of the present application relate to the technical field of antenna diversity, and in particular to a method and device for selecting a receiving mode based on signal diversity receiving. Background technique [0002] At present, with the development of communication technology, various communication devices have become indispensable for people's life. During the communication process, the communication equipment adopts the antenna to receive the communication signal. In order to ensure communication quality and reduce the impact of signal fading, in some communication scenarios, diversity technology will be used for signal transmission between the signal transmitter and receiver. Diversity technology is to use multiple signal paths that transmit the same information and have approximately equal average signal strength and independent fading characteristics, and properly combine these signals at the receiving end to greatly reduce the ...
