Abstract :
A digital implementation of an amplitude detector for Automatic Gain Control in a complex modulation format receiver is presented. The algorithm is based on the Co-Ordinate Rotation Digital Computer method which makes the amplitude detection very fast and accurate. The efficient topology enables realisation in a standard programmable gate array. Measurements on a 16QAM burst mode receiver are presented
