Abstract
In the paper, a concept of Additive Fuzzy Noise (AFN) channel is introduced. The theoretical equations are derived for Bit Error Rate (BER) and Symbol Error Rate (SER) with some digital modulation scheme in AFN channel. Following modulation are considered: Binary Phase Shift Keying (BPSK), Binary Frequency Shift Keying (BFSK), Pulse Amplitude Modulation (4PAM), Quadrature Phase Shift Keying (QPSK), Quadrature Amplitude Modulation (QAM). Fuzzy approach to these modulations is presented. The BER and SER values are calculated using possibility theory. The results obtained by fuzzy noise simulation are compared with conventional approach, where probability models are used.
