	Mobile Pipeline \| How MIMO Multiplies Wireless Capacity (Site not responding. Last check: 2007-10-26)
		MIMO is a multi-dimensional approach that transmits and receives two or more unique data streams through one radio channel whereby the system delivers two or more times the data rate per channel.
		MIMO is the only multiple antenna technique that increases spectral capacity by delivering two or more times the peak data rate of a system per channel or per MHz of spectrum.
		MIMO systems divide a data stream into multiple streams, each of which is modulated and transmitted through a different radio-antenna chain at the same time in the same frequency channel.

	How MIMO Works (Site not responding. Last check: 2007-10-26)
		MIMO systems divide a data stream into multiple unique streams, each of which is modulated and transmitted through a different radio-antenna chain at the same time in the same frequency channel.
		The data streams are separated at the receiver using MIMO algorithms that rely on estimates of all channels between each transmitter and each receiver.
		With MIMO, the maximum data rate per channel grows linearly with the number of different data streams that are transmitted in the same channel.

	What is MIMO? - a definition from Whatis.com
		- MIMO (multiple input, multiple output) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver).
		MIMO is one of several forms of smart antenna technology, the others being MISO (multiple input, single output) and SIMO (single input, multiple output).
		MIMO technology has aroused interest because of its possible applications in digital television (DTV), wireless local area networks (WLANs), metropolitan area networks (MANs), and mobile communications.

	MIMO - Demystifying Physical Layer Issues with MIMO - multiple input, multiple output, mimo
		This is accomplished in a MIMO system by exploiting the spatial dimensions and increasing the number of signal paths between the transmitters and the receivers.
		This means that by using a MIMO system, wireless network operators can increase their broadband services within the currently allocated spectrum without having to expand to more spectrums.
		For each composite data packet received, the MIMO decoder must be able to estimate the channel transfer matrix [H] during the MIMO preamble of the packet.

	Agilent \| MIMO
		MIMO (Multiple-Input Multiple-Output) radio uses a number of techniques to make more effective use of the RF spectrum.
		MIMO radio works by taking advantage of the multiple paths a radio signal takes between the transmitter and receiver.
		The technique of separating out different paths in the radio link is what allows the MIMO radio to transmit multiple signals at the same time on the same frequency, and thereby improve the use of the spectrum.

	MIMO Architecture for Wireless Communication
		In this section, we present the capacity of wireless MIMO channels and show that it is greater than that of the wireline SISO channel.
		This is not the case for wireless MIMO channels as shown next.
		Usually, MIMO systems are used to simultaneously achieve both increased throughput and reduced power.

	Audio DesignLine \| SDR Meets MIMO Tutorial
		MIMO has the ability to significantly increase raw data throughput in spectrally limited environments, while at the same time providing immunity to the multipath effects common in urban settings.
		Given the benefits inherent in a MIMO based architecture but something of a lack of maturity in MIMO technology, a question is raised as to how MIMO capabilities can be inserted into radio systems in a cost effective manner after those radios are already in service.
		Data in a MIMO system is transmitted over T transmit antennas through what is referred to as a "MIMO channel" to R receive antennas supported by the receiver terminal (see Figure 1).

	USATODAY.com - New wireless technology kills 'dead spots' at home (Site not responding. Last check: 2007-10-26)
		Mimo is expected to be at the forefront of the speedy next iteration of Wi-Fi, known in geek-speak as "802.11n." The engineers won't finalize the precise standard until next year, which means there's no guarantee today's Mimo devices will get along with whatever the industry eventually cooks up.
		But Mimo's improvements are dramatic, and the technology already makes nice with the most popular current flavors of Wi-Fi, 802.11b and 802.11g.
		Here's a simplified version of how Mimo works: For about a century, scientists have wanted to mitigate a natural phenomenon known as "multipath." That's when transmitted radio signals bounce off barriers and take multiple paths to get to a receiver, resulting in interference.
