Narrowband and broadband integrated wireless cluster communication system and processing method thereof

Abstract

The present invention discloses a narrowband and broadband integrated wireless cluster communication system in the data radio station, interphone, cluster communication and wireless communication technology fields. The narrowband and broadband integrated wireless cluster communication system comprises a channel encoding module in electrical output connection with a SYM_MOD module, the SYM_MOD module is in electrical output connection with a sub-band mapping module, and the sub-band mapping module is in electrical output connection with an IFFT module. The IFFT module is in electrical output connection with a sub-phase time domain convolution module, the sub-phase time domain convolution module is in electrical output connection with a time domain signal sampling module, and the time domain signal sampling module is in electrical output connection with a unit delay module. A technical device provided by the present invention fully utilizes the aggregation and decomposition relation of a communication waveform of a narrowband cluster and a communication waveform of a broadband cluster, on the basis of rapid filter group transformation, dynamically adjusts the bandwidth of the system, and supports different businesses.

Description

technical field [0001] The invention relates to the technical fields of digital transmission stations, walkie-talkies, trunking communications and wireless communications, in particular to a wireless trunking communication system integrating narrowband and broadband and a processing method thereof. Background technique [0002] At present, the demand for trunking communication systems is still strong. In specific industries and occasions, the role of trunking communication is irreplaceable. They are carrying the work and utility that cannot be completed by other communication systems. However, compared with the traditional narrowband trunking system, the application requirements of the broadband trunking system are rapidly appearing in the market. In the process of this technology evolution, the seamless integration and docking of narrowband trunking and broadband trunking is very critical. For example: Can the transceivers of narrowband trunking and broadband trunking work...
