A Survey on DCSK-Based Communication Systems and Their Application to UWB Scenarios

In the past two decades, chaotic modulations have drawn a great deal of attention in low-power and low-complexity wireless communication applications due to their excellent anti-fading and anti-intercept capabilities. Of particular interest is the differential chaos shift keying (DCSK), which is considered as a very promising chaotic modulation scheme that achieves not only good error performance, but also low implementation complexity. In this...
