Abstract
A method of dynamically changing the list size of a successive cancellation list (SCL) decoder, the SCL decoder arranged to decode data received from a wireless communications system, the method comprising at each successive cancellation stage of the SCL decoder, determining a path metric of each path of the SCL decoder, selecting a differential path metric threshold, and dynamically changing the list size of the SCL decoder based on the differential path metric threshold and the path metric of each path of the cancellation stage, such that decoding sensitivity of the decoder is maintained and/or latency and error-correction performance of the decoder are balanced.
