The 3GPP LTE Turbo Decoder is a flexible, high performance and resource efficient implementation of the turbo convolutional decoding scheme defined in the 3GPP LTE specifications. A user specified number of parallel decoders are implemented in order to meet the challenging throughput and latency goals imposed by LTE. An intelligent scheduler optimizes the allocation of decode tasks across these parallel decode units. The 3GPP LTE Turbo Decoder can be used in conjunction with the 3GPP LTE Turbo Encoder core.
