Phase Distortion and Error Vector Magnitude for 8-PSK Systems
نویسندگان
چکیده
The demand for higher data rates in mobile communications is leading to the use of higher order modulation schemes, such as 8-PSK. In such systems distortion is a consequence of magnitude and phase disturbances. In this work we investigate the performance of an 8-PSK with phase distortion due to Gaussian bandpass noise, through analytical and simulation studies. Results are presented relating EVM to SER and to Es/No.

Effects of Magnitude and Phase Distortion in 8-PSK Systems on Error Vector Magnitude Measurements
This work investigates the effects of magnitude and/or phase distortions, in 8-Phase Shift Keying (8-PSK) systems, due to Gaussian bandpass noise. Analytical expressions are derived to compute the performance of the distorted 8-PSK signals in terms of error vector magnitude (EVM), symbol error rate (SER) and Es/No. The results show that the same value of EVM may result in different SER values d...
متن کاملEffect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...

متن کاملDesign of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
متن کاملOn linear structure and phase rotation invariant properties of block M-PSK modulation codes
In this correspondence, we investigate two important structural properties of block 2tary PSK modulation codes, namely: linear structure and phase symmetry. For an AWGN channel, the error performance of a modulation code depends on its squared Euclidean distance distribution. Linear structure of a code makes the error performance analysis much easier. Phase symmetry of a code is important in re...
