8 States Triple Binary Convolutional Encoders for the Construction of Turbo Codes
View through CrossRef
This paper presents the rate 3/4 (triple-binary) memory 3 recursive and systematic convolutional encoders with a single shift register (TBEm3) implemented in the observer canonical form with the best frame error rate (FER) versus signal to noise ratio (SNR) performance in configuration turbo (parallel concatenated) The triple-binary turbo-codes (TBTC) were compared in terms of performance with the turbo-codes (TC) from the actual standards of communications, at the same turbo-coding rates of 3/5 and 3/4. Besides the very good FER/SNR performance, the TBTC present several other advantages that recommend them: an effect error floor low, latency diminution, more compact blocks lower delay caused by interleaving, the possibility to connect the encoder TBTC to modulation blocks of higher order.
