Chaotic Direct Sequence Spread Spectrum Software Defined Radio System Model Using LabView

Paper presents a simple mathematical construction for generating chaotic sequences from piecewise linear tent map. A method for generating maximum length pseudo-noise sequences is explained. Direct sequence-spread spectrum system model is built in LabView for software defined radio USRP transceiver system. Performance of multiple chaotic sequences is compared against maximum length sequences on software defined radio transceiver chain and shown that chaotic sequences have equal, in some cases, even better performance.
