Networking/Data Transmission
Broadcasting is commonly used in ad hoc networking to build routes to unknown destinations. In static topologies, broadcasting is rarely used - a routing path between any two nodes must only be learned once. In dynamic topologies (typified by high mobility) learned routes can be ephemeral. Mobility effects are exacerbated by network traffic, which increases forwarding delays at each hop on a routing path. With increasing mobility and network traffic, routes must be built at shorter intervals.
Current main memory system designs are severely limited by the traditional synchronous DRAM architecture. This architecture requires the memory controller to track the internal status of memory devices (chips) and schedule the timing of device operations. This rigidity has become an obstacle for integrating emerging memory technologies such as PCM into existing memory systems--PCM requirements are vastly different.
This invention provides a new method of simultaneously addressing two major problems in high-capacity wireless communications: signal fading and interference. The technology consists of a new signal control algorithm that reformulates the minimum mean squared error (MMSE) criterion. Adaptive receivers for interference suppression based on the standard MMSE criterion fail over fading channels.
