Antennas Everywhere


A simple rule when it comes to electronics is that while digital circuits scale, antennas do not. That may not sound like a serious problem until you consider that as more devices get connected—cars, watches, industrial equipment—and they add more features that require interaction with the outside world, they need more antennas to make it all work. In the future, there literally will be... » read more

MIMO Maximum Likelihood Detector


MIMO (Multiple Input and Multiple Output) is one of the leading approaches for improving data rates and/or SNR (Signal to Noise Ratio). By using multiple receive and transmit antennas, MIMO can exploit the diversity of the wireless channel. This is then used to increase the spectral efficiency of the channel and improve the data rates for any given channel bandwidth. This white paper reviews... » read more

Talk, Talk And More Talk


By Ed Sperling To anyone who owns a cell phone—and there are at least several billion people who claim that distinction these days—it’s not surprising that bad reception lowers battery life. More bars, while not the most accurate gauge of a signal, are at least an indication that you can extend the time between charges even if you’re watching streaming video. But work is under way a... » read more
