Diversity reception method and device based on synchronization sequence

Abstract

The invention discloses a diversity reception method based synchronous sequence. Radio signal frame has at least two continuous synchronous sequences. For each branch there are sliding related step, delay step, conjugate multiplication step, step of computing diversity detection value and outputting diversity detection signal. Comparing diversity detection signal of each branch, maximum value branch is selected as diversity output branch. The invention overcomes deficiency of existing technology of complex computation, long-time delay for antenna switch, high error rate, provides a simplified diversity reception method for timingly switching diversity antenna, effectively resisting multi-path fading and doppler effect, improving error rate property, which can be widely used in wireless mobile communication field.

AI Technical Summary

Benefits of technology

The technical effects provided by this new technology are that it can simplify receiving signals more efficiently without affecting their quality or reliability due to multiple paths between them. This makes communication faster over wireless networks even better than previous methods.

Problems solved by technology

Technologies described involve selecting which one of many receivers should receive data simultaneover when there are different sources of interference called co-interferers. Current techniques require calculating both the mean SNR and the minimum Sign Noise Power Ratio (SNPR). These conventional approaches have limitations due to factors like varying levels of background radio wave activity nearer than desired ones.
