Abstract

The embodiment of the invention discloses a signal diversity combining mode switching method and device. According to the technical scheme provided by the embodiment of the invention, the method comprises the steps: querying the binding relationship between the pre-stored diversity combination mode and the information of the signal transmitting end through the signal transmitting end, determiningthe corresponding diversity combination mode as the signal combination operation mode to perform signal combination of the signal copies, extracting a corresponding signal copy according to the set number of pieces of information sent by the signal transmitting end, performing signal combination by using each diversity combination mode to obtain a plurality of corresponding combined signals, evaluating the signal combination performance of each diversity combination mode according to each combined signal to obtain a corresponding performance evaluation result, and switching a current signal combination operation mode according to the performance evaluation result, and modifying the corresponding binding relationship. By adopting the technical means, the signal diversity combining mode canbe adaptively switched in real time, the signal receiving quality is guaranteed in real time, and the signal combining processing effect is optimized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of diversity reception, and in particular to a method and device for switching a signal diversity combining mode. 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 of communication equipment, in order to ensure the quality of communication, reduce the impact of signal fading, and ensure the quality of signal transmission, diversity technology is usually 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 impact of multipath fading, thereby improving transmis...
