In this paper, performance analysis for different combining technique for receiver diversity in a MIMO system is presented. A general framework for diversity combining techniques in cooperative ...
Free Space Optics is the technology which implies the line-of-sight link for the transfer of data between two distant points. The beam of light is used to provide optical connection that can transmit ...
This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design, ...
Since the early days of electronics, as advances in technology were taking place, the boundaries of both local and global communication began eroding, resulting in a world that is smaller and hence ...
Fig 1. A DP-QPSK transmitter and a coherent receiver with ADC and DSP are key analog components for long-distance transmission systems. Fig 2. Shown is the measured (blue, green) and simulated (red) ...
In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...
Quadrature phase shift key is a one of the digital modulation schemes that use Phase-shift keying. One popular varient of QPSK is offset QPSK or OQPSK. What is the difference between these two ...
