متن کاملSource Turbo Encoder Channel Sink Turbo Decoder BPSK
Abstra t | In this work, we investigate the joint sour ehannel oding issue of transmitting non-uniform independent and identi ally distributed (i.i.d.) sour es over additive white Gaussian noise (AWGN) hannels via Turbo odes. The sour e redundan y in the form of non-uniformity is exploited in the Turbo de oder via a modi ed extrinsi information. In ontrast to previous work, non-systemati re urs...
متن کاملImplementation of Efficient Turbo Code Encoder-decoder with Max-log-map Algorithm
Turbo Codes are very flexible codes and it can be considered as one of the great achievements in the field of communication systems. Turbo Codes have been adopted for wireless digital communication system and they remain unaffected even under heavy traffic situation. The MAX-Log MAP Algorithm which performs necessary computation in Log domain has the capacity to reduce hardware complexity. Majo...
متن کاملBLIND PARAMETER ESTIMATION OF A RATE k/n CONVOLUTIONAL CODE IN NOISELESS CASE
This paper concerns to blind identification of a convolutional code with desired rate in a noiseless transmission scenario. To the best of our knowledge, blind estimation of convolutional code based on only the received bitstream doesn’t lead to a unique solution. Hence, without loss of generality, we will assume that the transmitter employs a non-catastrophic encoder. Moreover, we consider a c...
