Abstract

The invention discloses a handheld wireless ad hoc network communication device. A baseband processing module of the handheld wireless ad hoc network communication device comprises: a modulator/demodulator which is used for modulating/demodulating a signal frame; the modulator/demodulator adopts an OFDM (Orthogonal Frequency Division Multiplexing)/OQAM (Open Quadrature Amplitude Modulation) modulation/demodulation mode, various problems of handheld ad hoc network communication equipment in the prior art are solved, and real number symbols, real parts and imaginary parts which are subjected tooffset processing are modulated and sent instead of complex symbols; the handheld wireless ad hoc network communication device has excellent performance in the aspects of spectrum efficiency, ICI resistance, out-of-band radiation and the like, and solves the problems in the prior art.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a handheld wireless ad hoc network communication device. Background technique [0002] The wireless ad hoc network is a multi-hop temporary autonomous system developed from the Packet Radio Network (PRN). Its prototype is the ALOHA computer communication network established by the University of Hawaii in 1968 and the US Department of Defense in 1973. The Packet Radio Network project initiated by the Advanced Research Projects Agency (DARPA). With the transformation of military tactical strategies around the world, ad hoc network technology has been paid more and more attention, and has become the technical basis for the intercommunication of various information systems and information services, and has been widely used in the military field. The wireless self-organizing network has the following characteristics. One is to use the grouping mechanism in th...
