- Abstract
- In this paper, we propose a method of mixing modulation schemes to make it very difficult to intercept information from frequency hopping signals and assess analytically the difficulty of information interception using the interceptor computational complexity as a metric. In particular, we consider, to illustrate the effectiveness of mixing modulation schemes for secure communications, a method of randomly mixing BPSK and QPSK modulations in frequency hopping systems and compare it with conventional frequency hopping systems using BPSK only or QPSK only modulation scheme by deriving simple to evaluate upper and lower bounds on the interceptor complexity.
