Viterbi decoding method using channel state information in COFDM system
A Viterbi decoder using channel state information (CSI) is presented in a digital terrestrial television broadcasting system. The proposed Viterbi decoder uses the CSI derived from the pilots and CSI is calculated by interpolation method using the pilots in the receiver. We simulated this method in...

| description | A Viterbi decoder using channel state information (CSI) is presented in a digital terrestrial television broadcasting system. The proposed Viterbi decoder uses the CSI derived from the pilots and CSI is calculated by interpolation method using the pilots in the receiver. We simulated this method in Rayleigh fading defined in ETSI standard. From the simulation, we obtained the results that this method has a better performance of about 0.15 dB to 0.7 dB and 2.2 dB to 2.9 dB in the Rayleigh channel than that of the conventional soft decision Viterbi decoding with or without bit interleaver where the constellation is QPSK, 16-QAM and 64-QAM. |
