Abstract
An packet detection controller accepts an input from an AGC controller which indicates the presence of an increased signal energy and also completion of an AGC process and generates an output to suspend the AGC process. The packet detection controller also receives a plurality of IQ receiver streams and forms a single stream for use by a packet detector, which is controllable by an SNR_MODE indicating whether the signal to noise ratio is above or below a particular threshold, and a PD_RESET signal indicating that no packet detection should occur. The controller also receives a PACKET_DET signal indicating that packet detection is completed. The packet detection controller examines the incoming receiver streams and suspends AGC process if a packet detect is generated, or suspends the packet detector if an AGC process is required.
