Design a modulation and coding scheme for a wireless communication system. The system requires spectral efficiency 2.4 bits/symbol. 8-PSK modulations and (n=63, k=51, t=2) linear code, (n=63, k=36, t=5) linear block code, (n=63, k=24, t=7) linear block code and (n=63, k=16, t=11) linear block code are to be considered, where t is the number of errors which the code can correct.
The desired bit error rate is 6x10^-5 at Eb/No = 10dB what modulation/coding scheme gives the best performance which meets the specifications?© BrainMass Inc. brainmass.com October 10, 2019, 4:57 am ad1c9bdddf
The exact BER is hard to get because it really depends on the mapping codewords. So, a variety of BER approximation has been used. This solution used the BER approximation used in sol1.doc.
The detail of the solution can be found in the attached file. Thank ...
Bit error rate for given modulation/coding schemes is calculated in this solution. The best modulation/coding scheme is selected to satisfy the target BER. The solution is provided in a .pdf attachment.
