Abstract: Space-time codes are usually generated using a generator matrix with 2 columns and mod 4 operations for QPSK modulation with two transmit antennas. A Z 4 convolutional code has also been ...

Experiments show that Turbo code works better than convolutional code from all these three aspects, especially under the condition of low Signal-to-Noise Ratio(SNR). Published in: 2013 5th IEEE ...
