Bit Error Rate Estimation For Turbo Decoding

Set the frame length to 500. We show that, differently to previous techniques, the proposed estimation method is insensitive to such SNR estimation error. Please try the request again. Here are the instructions how to enable JavaScript in your web browser. check my blog

This year the conference received 115 submissions from 27 countries indicating that PWC is a reference conference for worldwide researchers from the wireless and mobile community. Because the bit mapping from the % demodulator is opposite that expected by the turbo decoder, the % decoder input must use the inverse of demodulated signal.
