Abstract
At a transmitter, a measurement array is constructed from various combinations of frame bits, including at least one combination Which includes many frame bits and at least one combination which includes only a few frame bits. The measurement array is transmitted along with the frame bits. Upon receipt of the frame at a receiver, a parity check is performed on the received frame bits and on the measurement array, resulting in the creation of a symptomatic array. The symptomatic array can be accumulated during the course of successive frames. After a sufficiently high number of frames, it will become clear from the values of the elements in the accumulated symptomatic array which bits in the symptomatic array are saturated and which are not. The accumulated symptomatic array is then mapped to a BER estimate.
