Quadrature Amplitude Modulation All Optical Orthogonal Frequency Division Multiplexing-dense Wavelength Division Multiplexing-optical Wireless Communication System under Different Weather Conditions

This paper proposes an analytical model for evaluating the performance of dense wavelength division multiplexing (DWDM) for all optical orthogonal frequency division multiplexing (AO-OFDM) optical wireless channel. The investigated performance for proposed system is evaluated for the parameters  bit error rate (BER) and Q factor .The constellation diagrams, and bit error rate (BER) of the recei...

A Simple Approximation for the Symbol Error Rate of Triangular Quadrature Amplitude Modulation

In this paper, we consider the error performance of the regular triangular quadrature amplitude modulation (TQAM). In particular, using an accurate exponential bound of the complementary error function, we derive a simple approximation for the average symbol error rate (SER) of TQAM over Additive White Gaussian Noise (AWGN) and fading channels. The accuracy of our approach is verified by some s...

Some Variations on Craig’s Method for Calculating the Probability of Error in Quadrature Amplitude Modulation

This paper applies Craig’s method to the calculation of the average error probability of QAM transmission systems. In particular, a method for calculating the exact probability of error of a 32-point cross constellation is demonstrated.
