RECEIVER THAT RECONFIGURES BETWEEN ZERO INTERMEDIATE FREQUENCY AND DIRECT SAMPLING BASED ON CHANNEL CONDITIONS

摘要

A wireless device for receiving wireless signals based on channel conditions is described. The wireless device includes a direct sampling path used when operating in a direct sampling mode. The wireless device also includes a zero intermediate frequency path used when operating in a normal sampling mode. The wireless device further includes a first switch coupling a filter module input to an input of the direct sampling path and an input of the zero intermediate frequency path. The wireless device also includes a second coupling a filter module output to an output of the direct sampling path and an output of the zero intermediate frequency path. The first switch and the second switch are configured to switch between the direct sampling path and the zero intermediate frequency path based on a received signal power.
