摘要：
This paper proposes an implementation of a synchronization method for wireless communication systems using a pseudo-True Random Bit Generator (PTRBG) based on chaotic maps. Chaos is generated using Nested Piecewise Linear Maps (NPWLM) to improve the statistical degradation introduced due to finite word length processing. Synchronization of nested maps using the backward iteration algorithm is introduced. This algorithm uses a mathematically driven formula to determine the initial condition of the nested map at the receiver in order to synchronize with the map at the transmitter. The implementation test bed for the complete wireless communication system is based on a Chipcon wireless development kit [http://focus.ti.com/docs/toolsw/folders/print/cc1 110-cc1111dk.html] and an assessment of the pseudo- true random bits generated is performed using the NIST statistical test suite.(1)
