Problems solved by technology

Due to the poor anti-interference performance of BASK modulation, when the signal-to-noise ratio is low, the envelope detection method has a threshold effect, resulting in a high bit error rate of the system, while using the coherent detection method, the receiver needs to extract the synchronous carrier from the BASK signal , and the process of extracting the synchronous carrier is more complicated, resulting in a more complicated structure of the receiver

Abstract

The invention relates to a processing auxiliary information method, a processing auxiliary information device, an obtaining auxiliary information method and an obtaining auxiliary information device. The processing auxiliary information method comprises the steps that a received signal is filtered to obtain a binary phase shift keying (BPSK) signal, the BPSK signal carries an auxiliary information data series of burst transmission, the auxiliary information data series comprises free data and an auxiliary information data frame, the free data comprises continuous and the same data, the auxiliary information data frame comprises successively ranked auxiliary information check bits, symbol sync bits, auxiliary information data bits and parity bits; according to the BPSK signal, carrier synchronization is processed to obtain a carrier signal; a signal which is obtained by the carrier signal multiplying the BPSK signal processes periodicity integral clear, an integral clear result is sampled and decided to obtain the auxiliary information data series. BPSK is transmitted and received to the auxiliary information, and the error rate of the system and the complexity of a receiver are reduced.

Description

technical field [0001] The invention relates to the field of microelectronics, in particular to a method and device for processing auxiliary information, and a method and device for obtaining auxiliary information. Background technique [0002] When people communicate in large spaces such as conference rooms and stages, the sound energy emitted by natural sound sources (such as speeches, musical instruments, and singing) is limited, and the sound pressure level increases with the increase of the propagation distance. Rapid attenuation, coupled with the influence of environmental noise, makes the sound propagation distance shorter. Therefore, it is necessary to use a public address system to amplify the sound source, amplify the signal of the sound source, effectively increase the sound pressure level within the sound field range, and increase the sound the propagation distance. A common wireless public address system is mainly composed of wireless microphones, audio transmi...
