Abstract :
Signal code modulation (SCM) is a mixed analog-digital modulation technique that is proposed for relaying a digital communication signal over channels with different Signal-to-Noise Ratios (SNRs) and, in particular, provides an alternative method besides the traditional complete demodulation and re-modulation (Demod/Remod). In this paper, we derive the exact closed-form expressions for the bit error rate (BER) of SCM modulation scheme in additive white Gaussian noise (AWGN) channel and Nakagami fading channel. Furthermore, the diversity gain for SCM is defined.
