You can understand how MIMO works, at least in broad terms, with a simple thought experiment. Suppose you set up a transmitter with a single antenna and then move a receiver, also with a single antenna, far enough away for the reception to fade in and out once in a while. Such problems arise because the transmitted signal takes multiple routes to the receiver—some of it perhaps bouncing off a passing car, other parts reflecting off the steel beams of the building where the receiver is located. When the difference in length between two paths is half a wavelength (or three halves, or five halves, and so forth), the two waves will interfere destructively, clobbering the signal. MIMO sidesteps that pitfall by multiplying the number of possible paths between transmitter and receiver. Throw in some serious number crunching to process the digitized signals and you can achieve extraordinarily high data rates.
Avoiding problems in such cases typically requires some kind of feedback mechanism. Winner: Radio Revolutionaries.

Software-defined radio is one of those promising but elusive ideas that’s been anticipated for quite some time. The concept is elegantly simple: get rid of the specialized electronics used to process radio signals and instead do everything with software. The result, we’ve been promised, will be a universal wireless device that can seamlessly handle a range of frequencies, modulation techniques, and encoding schemes.
A cellphone based on software-defined radio would be lighter, smaller, cheaper, and more power efficient. We aren’t there yet, but software-defined radio is definitely coming. For cellular carriers, the advantage of such technology is clear. ”In the software radio base-station race, the clear winner is Vanu,” says David Murotake, a telecom engineer whose company, SCA Technica, of Nashua, N.H., focuses on security issues in software-defined radio.

With the USB 2.0 specification at 650 pages one could easily be put off just by the sheer size of the standard. This is only the beginning of a long list of associated standards for USB. There are USB Class Standards such as the HID Class Specification which details the common operation of devices (keyboards, mice etc) falling under the HID (Human Interface Devices) Class - only another 97 pages.
If you are designing a USB Host, then you have three Host Controller Interface Standards to choose from. None of these are detailed in the USB 2.0 Spec. The good news is you don’t even need to bother reading the entire USB standard. Some chapters were churned out by marketing, others aimed at the lower link layer normally taken care off by your USB controller IC and a couple aimed at host and hub developers. So now we can begin to read the parts of the standard relevant to our needs. The Universal Serial Bus is host controlled. الرئيسية - مترجم.
