- This scheme optimizes the BER performance of asymmetric turbo codes of both Waterfall region at lower SNR’s and error-floor region at higher SNR’s. The simulation results shows better BER performance of asymmetric turbo codes for block size of 128, 512 bits, code-rate of 1/2 and Maximum-A-Posteriori (MAP) decoding algorithm over AWGN ...
- Apply it to a 16-QAM modulation scheme with a rectangular signal constellation. Assume the carrier frequency is 100 times the bit rate. Add white Gaussian noise to the transmitted signal. Assuming we have perfect synchronization, count the number of errors, when signal-to-noise ratio per bit ranges between 0 and 20 dB. 7.17
- Also bit- error-rate, an important parameter in case of receiving signal, is analyzed with respect to SNR values. A comparative analysis of bit-error-rate is performed between three areas for same conditions which proves that LTE signal is well suited in a rural area than that of a suburban and urban area.

LDPC Encoder and Decoder. Create LDPC encoder and decoder System objects and set the parity check matrix according to Section 5.3.1 of the DVB-S.2 standard [ 1].You set the IterationTerminationCondition property to 'Parity check satisfied' to stop the decoder iterations when all the parity checks are satisfied, which reduces the decoding time.
