Just in time for Computex, chipmaker Qualcomm has announced a bunch of new products hailing from its Atheros subsidiary that broadens the chipmaker's portfolio beyond mobile devices and into the ...
The drive to increase wireless data rates within the limited radio frequency (RF) spectrum is leading to radios with capabilities beyond a single-input single-output (SISO) topology. SISO radio ...
In the first installment of this series, “The MIMO advantage,” I covered the basics of multiple input, multiple output (MIMO). In this installment, I’ll provide the high-level calculations for ...
Multiple-input multiple-output (MIMO) technology, the heart of the upcoming IEEE 802.11n standard, is the foundation for the next generation of Wi-Fi products. With the promise of greater throughput ...
All of today’s advanced radio networks, including mobile radio networks (3GPP UMTS with LTE) and wireless networks (WLAN), are subject to continuously growing expectations for data rates. Yet classic ...
This paper presents a spatial mapping which turns dual data streams of MIMO system into an equivalent single stream. It is achieved by shrinking the constellation of the secondary stream into that of ...
