Performance Evaluation using M-QAM Modulated Optical OFDM Signals

OFDM (Optical Orthogonal Frequency Division Multiplexing) in the optical domain is an emerging technology for fulfilling increased bit rate demand of real time sophisticated applications. In this work an optical OFDM system is designed using different M-ary QAM (Quadrature amplitude Modulation) techniques by varying M to 16, 65, 256. Performance evaluation has been carried in terms of SNR (Sign...

Error-free transmission of microring-modulated BPSK.

We demonstrate the generation of error-free binary-phase-shift-keyed (BPSK) data at 5 Gb/s using a silicon microring modulator. The microring-modulated BPSK signal is propagated at fiber lengths up to 80 km, maintaining error-free performance, while demonstrating resilience to chromatic dispersion. Bit-error-rate measurements and eye diagrams show near equivalent performance of a microring-base...

Performance evaluation of gated volumetric modulated arc therapy

Background: Aim of this study is to evaluate the accuracy of the gated volumetric modulated arc therapy (VMAT/RapidArc) using 2D planar dosimetry, DynaLog files and COMPASS 3D dosimetry system. Materials and Methods: Pre-treatment quality assurance of 10 gated VMAT plans was verified using 2D array and COMPASS 3D dosimetry system. Advantage of COMPASS over 2D planar is that it provides the clin...

Performance Evaluation of Ds/cdma Communications Systems Modulated with 2 -shift Bpsk over Multipath Rayleigh Fading Channels

In mobile communications, power is a very important factor and nonlinear amplification of power amplifiers cannot be avoided due to their high power efficiency. This article presents the performance of 2 -shift BPSK modulation scheme used in DS/SS/CDMA wireless communications over multipath Rayleigh fading channel and compares the performance with the performance of conventional BPSK CDMA syste...
