Abstract

The invention relates to the technical field of communication, in particular to a multi-antenna single-carrier frequency domain equalization simplification device and algorithm, comprising a multi-antenna beam forming processing module, the multi-antenna beam forming processing module comprises an antenna array receiver module, an analog-to-digital converter, a digital beam former and a beam controller; the multi-antenna beamforming processing module carries out channel estimation according to a predicted reference signal and a received reference signal, and finally forms a weight of network beamforming through a beamforming algorithm root; according to the method, weighted combination of the received signals is completed by using the weighting factor of beam forming, and the signals subjected to weighted combination are uniformly subjected to synchronous processing, so that the complexity of multi-antenna parallel synchronization is simplified, the influence of noise on synchronization can be better resisted after weighted combination, and the synchronization is more accurate and has very strong creativity.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-antenna single-carrier frequency-domain equalization simplification device and algorithm. Background technique [0002] The smart antenna array is composed of multiple antenna units, and each antenna is followed by a complex weighting device, and finally the output is combined by an adder. The smart antenna with this structure can only complete airspace processing. The structure of smart antennas with both space and time domain processing capabilities is relatively complex, and each antenna is connected with a delay tap weighting network. The main meaning of adaptive or intelligent means that these weighting coefficients can be adaptively updated and adjusted according to a certain adaptive algorithm. [0003] The basic problem to be solved by the smart antenna array is anti-jamming and improving the channel gain of the desired signal. Anti-interference refers t...
