Traditionally, codec implementation complexity has been measured with a software implementation in mind. We address the VLSI implementation issues for the design of a class of error correcting codes - Low Density Parity Check Codes (LDPCs). Keeping hardware implementation issues in mind, we propose a heuristic algorithm to design an LDPC code. We also motivate the case for multi-rate LDPC coding/decoding and propose a reconfigurable VLSI architecture for multirate LDPC decoders. In addition, we describe a heuristic algorithm that computes an effective LDPC code of any given rate which by construction can be implemented on our reconfigurable LDPC decoder
