802.11n: MIMO really needs smart antennas
As Wi-Fi standards go, 802.11n has a lot to live up to, especially after hearing how 802.11n's advertised throughput, security, and reliability will allow Wi-Fi to replace existing wired networks. This means 802.11n's RF technology needs to be rock-solid, just like Ethernet cables, while facing ever-changing environmental conditions. ...

iMAT: MIMO without multiple antennas
Antenna systems are not normally a preeminent topic when it comes to discussions about wireless equipment. That attitude is completely understandable; antennas are just not that interesting to most people. To some, including myself, RF propagation and antenna technology are very worthy discussion topics. My fascination started 40 years ago...

Metamaterial: the unnatural composite is transforming wireless technology
I get excited when I read about how scientists are able to create experimental conditions that do not occur normally in nature. Recently I was digesting an article on the PhysicsWorld website about how physicists have developed a method using a new class of materials called metamaterial to bring light...

802.11n, MIMO, and multipath environments
In two previous posts-Multipath environments and how they affect Wi-Fi propagation and How to make the best of 802.11 multipath environments-I examined the somewhat nebulous topic of multipath fading and technologies that minimize the negative effects on Wi-Fi networks. Now I'm going to pull a 180 and talk about how...

Performance Enhancement of WLAN Using 802.11n and MIMO Technology
802.11n is IEEE wireless standards that significantly improve throughput and range of Wireless Local Area Networks WLAN compared with other 802.11 standards. It is expected to provide a throughput of over 100 Mbps, which is twice that of 802.11g. This difference is because it is designed to operate in both...

Multi-User Adaptive Resource Allocation Scheme for WLAN OFDM-MIMO Transmission
Orthogonal Frequency Division Multiplexing OFDM has recently been proposed for use in high data-rate wireless systems. OFDM has an important property of spectrum utilization technique that distributes each tone, which is orthogonal with every other tone. The system capacity can be significantly improved by multiple transmit and receive antennas that...

Novel Tap-Wise LMMSE Channel Estimation for MIMO W-CDMA
In this paper, a tap-wise LMMSE channel estimator for MIMO W-CDMA is derived. Descrambling operations applied to delayed versions of the received signal whiten the input signal. The descrambling process thus breaks up the full channel autocorrelation matrix including spatial and temporal correlation into several independent, small autocorrelation matrices that...
