The increasing number of users of mobile communication systems and the corresponding need for increased capacity show the importance of using a modulation scheme which is both power and bandwidth efficient. Continuous phase modulation (CPM) provides an attractive option for spectral efficient communication systems. Low-density parity-check (LDPC) codes combined with CPM has a potential to result in...
In this paper, in order to improve bit error performance, bandwidth efficiency and reduction of complexity compared to related schemes such as turbo codes, we combine low-density parity-check (LDPC) codes and continuous phase modulation (CPM) and introduce a new scheme, called LDPC coded CPM (LDPCC-CPM). At the receiver, an iterative detection method based on SISO algorithm is proposed. Then the effect...
Continuous Phase Modulation (CPM) provides an attractive option for spectral efficient communication systems. Low-Density Parity-Check Code (LDPCC) combined with CPM has a potential to result in a spectrally efficient scheme that is also energy efficient in that it yields low error rates at low signal-to-noise ratios. In this paper we consider the concatenation of a LDPC encoder and a CPM modulator...
