Abstract This article proposes a cooperative jamming (CJ) architecture based on the coded signal of interest (SOI). The CJ is superimposed on the coded SOI directly at the transmitter, and the authorized user reconstructs the received signal and canc

Antenna arrays with high directivity, low side-lobe level, and null control in desired direction and whip antenna with wider bandwidth both need to be optimized to meet different needs of communication systems. A new natural heuristic algorithm simul
