Architecture of single channel memory controller to support high bandwidth memory of pseudo channel mode or legacy mode

Abstract: Embodiments of the invention provide an approach to implement a single architecture to support high bandwidth memory of pseudo channel mode or legacy channel mode by using a single command channel and single data channel. An address mapping method forces each port transaction to alternatively split to two pseudo channels. Compared to the conventional pseudo channel architecture, the single architecture and pseudo channel rotation eliminates the need for duplicated command traffic logic, and a time division command arbitrator, which greatly reduces both control logic and power consumption of the circuits. Furthermore, pseudo channel rotation improves the utilization of memory bandwidth because the address mapping improves synchronization of the two pseudo channel traffics.

Capacity simulation and analysis of an IEEE 802.11n system in a residential house

Abstract: This paper presents an analysis of the Multiple-Input Multiple-Output (MIMO) capacity based on channel sounding measurements in a residential house. Specular and dense multipath components are estimated from the channel sounding data with the RiMAX maximum-likelihood algorithm. These multipath channels serve as input for the capacity calculations. Specifically, capacity calculations are done for a 2 × 2 MIMO system that uses the legacy mode of the IEEE 802.11n standard.

Multi-carrier grant design

Abstract: Systems and methodologies are described that facilitate assigning resources for an anchor carrier and an additional carrier with a grant message. The grant message communicated with an anchor carrier can include resource information a plurality of carriers. Moreover, the systems and methodologies that facilitate identifying control information for an anchor carrier and/or an additional carrier based upon an operating mode, wherein the operating mode is a legacy mode or an extended mode. Based on the operating mode, particular resources associated with control regions are monitored for control information for respective anchor carrier(s) or additional carrier(s).
