OFDM system is promising technology for high speed data communication in wireless media. In this paper OFDM system model is developed over flat fading channel with Additive Gaussian White Noise (AWGN). Initially BER analysis is carried out in OFDM system with the number of sub-carriers ‘N’ using M-ary PSK and M-ary QAM. Analysis is carried out with the number of sub-carriers (N=64) with Rayleig...

Images of fuzzy relations provide powerful access to fuzzifications of properties of and/or relationships between fuzzy sets. As an important example, images of fuzzy orderings canonically lead to a concept of ordering of fuzzy sets. This contribution studies in which way the partial (i.e. componentwise) monotonicity of an n-ary mapping transfers to its extension to fuzzy sets.
