MIMO systems (with multiple transmit and receive antennas) are becoming increasingly popular, and many next-generation systems such as WiMAX, 3-GPP LTE and IEEE802.11n wireless LANs relay on the increased throughput of MIMO systems with up to four antennas at receiver and transmitter. High throughput implementation of the detection unit for MIMO systems is a significant challenge especially for higher...
Future high speed wireless standards such as 802.11n involve multiple input multiple output (MIMO) antenna systems as a key technology component. Efficient design of the MIMO detector is a challenging task. This is further compounded by the fact that 802.11n standard requires support for runtime switching between different modulation schemes (or modes). While searching for an appropriate architecture...
Upcoming wireless communication standards such as 802.11 n, WiMax etc require support for multiple modulation schemes. These standards all have multiple transmit and receive antennas(MIMO). Hence, the MIMO detector hardware should be able to accommodate different modulation schemes preferably on a single reconfigurable architecture. This paper presents an high performance FPGA implementation of a...

Multiple Input Multiple Output (MIMO) system is a key technology for future high speed wireless communication standards like 802.11n, WIGWAM, and WiMax. These standards require support for multiple modulation and coding schemes. Hence, the receiver hardware should be able to accomodate these schemes preferably on a single reconfigurable architecture. Current MIMO detector implementations are constrained...
Dirty paper code (DPC) can be used in a number of communication network applications; broadcast channels, multiuser interference channels and ISI channels to name a few. We study various implementation bottlenecks and issues with implementing a DPC pre-coder based on nested trellis technique. The aim is to achieve a practical hardware realization of the precoder for wireless LAN/DSL applications....
