This paper presents a new communication scheme, named quadrature differential chaotic phase shift keying (QDCPSK), which is developed from M-ary phase shift keying, chaotic phase and quadrature chaos shift keying (QCSK). It has not only the advances and characteristics of chaotic communication systems, but also higher efficiency of band usage and(More)
This paper presents a MIMO system scheme which is combined with STBC and V-BLAST. It can balance spatial multiplexing gain and diversity gain. Then, according to theory, a result is provided by a simple simulation analyze. In addition, for the application to ad hoc networks, a CSMA/TDCA protocol, which avoids the collision through a mode of time slot(More)
