Methods and apparatus for estimating interference level in a receiver are dominated by the receiver's residual frequency error when the interference is low. The interference estimation method can be changed when the interference is low such that it compensates for the effects of resi
Methods and apparatus are described for estimating a path-loss difference between uplink and downlink communications at a first node communicating with a second node in a communication system. A quantity of access request preambles transmitted by the first node to the second node before
An automatic frequency control (AFC) system in an electronic device is operated by using an AFC-algorithm component to determine a frequency error corresponding to a difference between a frequency of a signal output from a signal generator and a received signal frequency. The frequen
