Abstract: A receiver circuit has a chain of stream processing circuits (10a-c)—having control parameter inputs for receiving control parameter values. To facilitate design of circuits that receive data with a variable block size, an included control circuit (14) selects block sizes of blocks of samples in the respective streams of a plurality of the stream processing circuits (10a-c), a control parameter value for each particular block. The control circuit transmits instructions specifying the selected block sizes and control parameter values to local control circuits (11). Each local control circuit is coupled to the control circuit (14) and the control input of a respective corresponding stream processing circuit (10a-c). Each local control circuit (11) receives at least part of the instructions and applies parameter values from the instructions to its corresponding stream processing circuit (10a-c). The local control circuit (11) controls timing of control parameter updates using block sizes from the instructions.

Abstract: In order to find the position of the boundary between transmitted codewords, in a receiver a reliability measure for two possible positions are compared. If a relative difference measure of these reliability measure exceeds a predetermined threshold value, the reliability measure indicating the largest reliability corresponds to the correct position of the boundary between the codewords.
