Popis
Shrnutí:In this paper a high speed turbo product code (TPC) decoder based on fast Chase algorithm is proposed. The improvement in speed is achieved by exploiting the parallelism in the decoder design. A fully parallel soft-in soft-out (SISO) module based on low complexity fast Chase algorithm is designed. The designed parallel SISO module is used to construct the turbo product decoder using sub block parallelism without any interleaving resources. With this design, a 15 times increase in speed is achieved with a (31,26)^{2} Hamming TPC when compared to that of the decoder that uses sequential SISO module with barrel shifter as interleaving resource. However there is a marginal increase in the area utilized. It is envisaged that, with the use of area efficient adders and comparators, the speed-area trade-off can be mitigated.
