Hi,
I am implementing an OFDM modulation scheme as part of an LTE project in C/C++ and then testing it on a DSP board. I am using turbo coding with soft decision decoding. On the receiver side of the LTE system, I need to perform a soft demodulation (16-QAM and 64-QAM) so I can feed real values to the turbo coder for decoding. I have looked for information about soft demodulation on the Internet but didn't find any helpful ones. Does anyone know of a book or journal paper or any source of information that explains the soft demodulation (QPSK, 16-QAM, or 64-QAM)?
Any input is much appreciated. Thanks.
