Abstract

The invention discloses an analytical method of transmitted diversity signals, which comprises the steps of: grouping antennae according to the strength of received signals; computing the weight of each group of antennae; decoding the received signals of each group of antennae; multiplying decoding results respectively by the weight of the antennae in the same group; and adding products of different groups. The invention also discloses a receiving device of transmitted diversity signals. By adopting the analytical method and the receiving device of the invention, the antennae of the receiving device are grouped so that the antennae of different performance qualities have different contributions to combined signals. Therefore, the combining optimization is embodied and the processing performance of the receiving device is enhanced.

Description

technical field [0001] The invention relates to the communication field, in particular to an analysis method and a receiving device for transmitting diversity signals. Background technique [0002] In wireless communication systems, the main factor affecting signal quality in the transmission environment is channel fading, and the use of transmit diversity technology can effectively combat wireless channel fading and provide reliable information transmission for the system. Moreover, the transmit diversity technology is simple to implement and can improve system performance without increasing the total transmit power. [0003] At present, on the side of the signal receiving end, the diversity combining methods for the transmit diversity technology include methods such as selection combining, handover combining, and equal gain combining. [0004] Among them, selection combining and switching combining are relatively simple in implementation, but some redundant information wi...
