Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Abstract: This letter presents the design, implementation, and validation of an FPGA-based phase offset estimation and compensation algorithm for RF communication systems. The algorithm improves the ...

Sixteen unique 16-QAM symbols can each convey a unique 4-bit sequence. You can map these positions in various ways, as long as both the transmitter and receiver know the details. Figure 1 shows one ...

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...

A constellation diagram plots a quadrature amplitude modulation (QAM) signal’s in-phase and quadrature components. The EE World article “Should I use a spectrum, signal, or vector network analyzer?” ...

The need for higher data rate and higher systems capacity leads to several solutions including higher constellation size, spatial multiplexing, adaptive modulation and Non-Orthogonal Multiple Access ...

Abstract: This work provides a comparative study of the 5G new radio (NR) polar coding with different symbol modulation techniques and different delay profiles of NLOS channel. It has been observed ...
