METHODS OF RECEIVING COMMUNICATIONS SIGNALS INCLUDING A PLURALITY OF DIGITAL FILTERS HAVING DIFFERENT BANDWIDTHS AND RELATED RECEIVERS

摘要

Methods of receiving communications signals can include generating a received analog signal including energy corresponding to communications transmitted from a remote transmitter, and performing an analog-to-digital conversion of the received analog signal to provide a received digital signal. The received digital signal can be digitally filtered using a first digital filter having a first bandwidth to provide a first filtered digital signal, and the first filtered digital signal can be processed to provide an estimate of the communications transmitted from the remote transmitter. The received digital signal can be digitally filtered using a second digital filter having a second bandwidth to provide a second filtered digital signal wherein the second bandwidth is greater than the first bandwidth, and a signal characteristic of the second filtered digital signal can be measured. Related receivers are also discussed.
