Implementation of a selector in VHDL

Multiplexers are very common in hardware design and generally FPGA configurable logic blocks have the hardware to support multiplexers natively. To take advantage of the dedicated hardware for the multiplexer…

Image Segmentation : K-Means Clustering Approach

We mentioned in a previous post (K-Means Clustering Introduction) that the K-Means Clustering algorithm can be used to recognize a soccer ball on a soccer field. We found we could use the K-Means Clustering algorithm to identity and group similar pixels into [\latex]$k$[/latex] groups. These groups are based on the RGB values of a pixel and with a simple example we saw with a 4-pixel image it was easy to determine which pixels are similar. In this post we will demonstrate image segmentation by identifying a soccer ball on a grassy field. (more…)

5G Physical Layer Intro

5G (fifth generation) mobile wireless communications standards are published. From the standards companies can start developing applications that adhere to the 5G standard. We will see emerging devices saying they are 5G capable. But what does that mean? Is it faster? More reliable? Do I care? Is it just some business rebranding to generate more money? To understand the answers to these questions we need to first understand the underlying technology for 5G Physical Layer wireless data transfer.

What is 5G Massive MIMO

5G or Fifth Generation mobile communications standards are out. Some wireless communications technology that is being leveraged in the standard promise to make 5G communications faster, more reliable, and more agile in tough wireless environments. 5G benefits from massive MIMO technology to provide its next generation data rates.
