Turbo coding is an advanced error correction technique widely used in the communications industry. Turbo encoders and decoders are key elements in today's communication systems to achieve the best possible data reception with least possible errors. The basis of turbo coding is to introduce redundancy in the data to be transmitted through a channel. The redundant data helps to recover original data from the received data.
Lattice's Turbo Encoder IP Core is compliant with three different standards: 3GPP, 3GPP2, and CCSDS. The 3GPP and 3GPP2 standards are widely used in WCDMA and MC-CDMA applications while CCSDS is most commonly found in telemetry and space communications. Each one of these encoders is a separate entity as the interleaver and control logic for each encoder is completely different.
Lattice's Turbo Encoder core is created in conjunction with the Turbo Decoder core to provide users with a state of the art error correction technique.
