چکیده

Jaeyoon Lee et al. 707 In-phase/quadrature (I/Q) imbalances, which are generated by non-ideal transceiver components, are inevitable physical phenomena that cause the performance of practical communication systems to be degraded. In this paper, we provide a new closed-form expression for the bit error rate of hierarchical M-ary phase shift keying with I/Q phase and amplitude imbalances and analyze the effect of I/Q imbalances on BER performance over an additive white Gaussian noise channel.

Simulink Based Comparative Analysis of M-ary Phase Shift Keying Modulation Schemes

This paper focuses mainly on Bit Error Rate(BER) and Signal to Noise Ratio(SNR).To analyse the system’s performance probability of error plays a major role. Each modulation technique has its own performance while dealing with signals corrupted with noise. This paper describes the comparative analysis of basic M-ary Phase Shift Keying modulation schemes like BPSK, QPSK,8-PSK and 16-PSK. It gives...

Multilevel code-shifted differential-chaos-shift-keying system

The M -ary differential-chaos-shift-keying (M -ary DCSK) system offers a good noise performance over an additive white Gaussian noise (AWGN) channel in the category of non-coherent detection chaotic systems. However, the way that the M -ary DCSK system utilizes the available Walsh codes results in a relatively low bandwidth efficiency. Moreover, the number of delay elements required at the tran...

Performance Evaluation of Optically Preamplified M -

M -ary pulse position modulation (M -ary PPM) has been widely considered as an attractive solution for increasing the bit rates in free-space optical (FSO) communications. Besides increasing the bit rate, M -ary PPM increases the power efficiency of FSO systems. Hence, better performance can be achieved at lower Eb/N0 values when compared to on-off keying (OOK). M -ary PPM systems can be implem...
