Abstract: An encoder module (400) includes P/L parity shift registers (403, 403', 403") that are sequentially coupled, wherein an input of a first parity shift register (403') of the parity shift registers (403, 403', 403") is coupled to the input (D in ) of the encoder module (400), an output of the last parity shift register (403") of the parity shift registers (403, 403', 403") is coupled to the output (D out ) of the encoder module (400), each of the parity shift registers (403, 403', 403") being configured to store L parity digits. The encoder module (403) also includes a feedback circuit (405) comprising P/L parity generation modules (407), wherein each of the parity generation modules (407) is coupled to an output of a corresponding one of the parity shift registers (403, 403', 403") by a switch (S1, S2, S3, S4) and also coupled to the input of the first parity shift register (403'), wherein each of the parity generation modules (407) is configured to generate L parity digits for transmission to the input of the first parity shift register (403') when its corresponding switch is closed (S1, S2, S3, S4).
