This paper focuses on the optimization of performance of single-user chaos shift-keying (CSK) More efficient signal transmission is achieved in the coherent case by introducing the class of the so-called deformed circular maps for the generation of spreading. Also, the paired Bernoulli circular spreading (PBCS) us introduced as an optimal choice; which attains the lower bound of bit error rate (BER.) As interest shifts to the non-coherent version of the system; attention moves to the receiver end Maximum likelihood (ML) decoding is utilized serving as an improvement over the correlation decoder To make the methodology numerically realizable; a Monte Carlo likelihood approach is employed
