Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is further described as follows:

[0025] The overall technical solution of the present invention is to add a plurality of receiving nodes with their own antennas in space, and to significantly improve the receiving performance of the system by performing space diversity on the antennas. In channel coding, the information frame transmission mechanism is used, which is beneficial to detect and correct the error of a single information frame. Through a wireless management host, multiple receiving processing modules are built in to perform re-diversity processing on the verification information frame sequences of multiple receiving nodes, and vote to obtain a valid data frame.

[0026] The wireless communication diversity processing system consists of a wireless data transmitting unit, multiple wireless data receiving nodes, a wireless management host and a system host.

Abstract

The invention discloses a wireless communication diversity processing system. A plurality of additional receiving nodes with antennae are arranged spatially, so the receiving performance of the system is remarkably improved by spatial diversity. An information frame transmission mechanism is adopted for channel coding, and is favorable for detecting and correcting errors of a single information frame. A plurality of built-in receiving processing modules of a wireless management host perform diversity processing on a check information frame sequence of the plurality of receiving nodes, and vote to obtain a valid data frame.

Description

technical field [0001] The invention relates to a wireless communication diversity processing system, in particular, the system adopts a diversity processing method which is different from traditional diversity firmware and takes data packets as units. Background technique [0002] The biggest feature of wireless communication is the multipath effect. The received signal at the wireless receiving end includes Doppler frequency shift and deep attenuation, as well as time delay. How to receive high-speed communication data timely and accurately is the basic technical problem of wireless communication system. The diversity methods used in the placement of antennas in general wireless communication systems include (1) space diversity: the received signals of different antennas are independent of each other; (2) polarization diversity: the signals of horizontal polarization and vertical polarization are independent of each other. The role of antenna diversity is mainly to ident...
