Claim Text:
1. A method for antenna activity detection in multi-antenna communication devices, the method comprising: computing a received signal strength indicator (RSSI) value for each of a plurality of antennas based on a sampled data associated with each of the plurality of antennas; identifying, from the plurality of antennas, an antenna having a highest RSSI value as a primary antenna and one or more antennas having the RSSI value less than the highest RSSI value as auxiliary antennas; calculating an RSSI difference for each of the auxiliary antennas, wherein the RSSI difference corresponding to an auxiliary antenna is a difference between the RSSI value corresponding to the primary antenna and the RSSI value corresponding to the auxiliary antenna; comparing the RSSI difference corresponding to each of the auxiliary antennas with a first threshold value to ascertain one or more potentially inactive antennas from among the auxiliary antennas; and identifying, from the one or more potentially inactive antennas, one or more inactive antennas based at least in part on the RSSI value by
