Abstract: A communication device can be configured to detect false positives of a decoded signal that have passed error detection. The communication device can include an error detector and a false positive detector. The error detector can detect an error of a decoded signal generated from an encoded signal, and output a payload of the decoded signal in response to the decoded signal passing the error detection. The false positive detector can calculate an estimated bit-error rate (BER) of the encoded signal and a predicted BER of the encoded signal. The false positive detector can determine a false positive of the error detection passing of the decoded signal based on the estimated BER and the predicted BER.

Abstract: A communication device can be configured to estimate a Reference-Signal-Received-Power (RSRP). The communication device can include a transceiver and a controller. The transceiver can be configured to downsample a received signal having a plurality of reference signal resource elements to generate a downsampled signal. The downsampling can alias a first of the plurality of reference signal resource elements into a second of the plurality of reference signal resource elements to generate an aliased reference signal resource element. The transceiver can also be configured to extract the aliased reference signal resource element from the downsampled signal. The controller can be connected to the transceiver and be configured to estimate the RSRP based on the extracted aliased reference signal resource element.

Abstract: A method and communication device adapted for interference cancellation in a cell search used in a communication device, including: correlating a signal received at the communication device with a template comprising one or more signal sequences associated with one or more corresponding cells to determine a metric for each of the signal sequences; and at least one iteration of: ranking the signal sequences based on the determined metrics, wherein the highest ranked signal sequence is designated as an aggressor sequence; performing an interference cancellation to generate a corrected metric for signal sequences based on their correlation with the aggressor sequence; and removing the aggressor sequence and setting priority to the cell associated with the aggressor sequence.
