Abstract: Disclosed is a satellite communication system that allocates bandwidth to maximize the capacity of the communication system while providing service to geographical areas having different demands. A smaller portion of the frequency spectrum can be allocated for subscriber beams that supply service to low demand areas.

Allocation of bandwidth can be determined by the amount of demand in low demand areas versus the amount of demand in high demand areas. High demand gateways are physically located in low demand subscriber beams, while low demand gateways are physically located in high demand subscriber beams, which prevents interference.

Abstract: A method and apparatus for improving channel estimation within an OFDM communication system. Channel estimation in OFDM is usually performed with the aid of pilot symbols. The pilot symbols are typically spaced in time and frequency. The set of frequencies and times at which pilot symbols are inserted is referred to as a pilot pattern. In some cases, the pilot pattern is a diagonal-shaped lattice, either regular or irregular. The method first interpolates in the direction of larger coherence (time or frequency). Using these measurements, the density of pilot symbols in the direction of faster change will be increased thereby improving channel estimation without increasing overhead. As such, the results of the first interpolating step can then be used to assist the interpolation in the dimension of smaller coherence (time or frequency).

Abstract: Particular embodiments change a current storage I/O path used by a host computer to access networked storage to an alternative storage I/O path by considering traffic load at a networked switch in the current storage I/O path. The host computer transmits a request to the networked switch in the current storage I/O path to provide network load information currently experiences by the networked switch.

Based on the evaluation, the host computer selects a new alternative storage I/O path to the networked storage that does not include the networked switch, and then forwards future storage I/O communications to the networked storage using the new alternative storage I/O path.

Abstract: A method is provided a wireless system for providing small “guard” cells in a heterogeneous network at locations proximate to privately-maintained HeNB (or femto) cells in the heterogeneous network. More particularly, the methodology of the invention addresses the problem of a mobile user in a heterogeneous network located nearby to a privately maintained HeNB cell in the heterogeneous network, and the inherent interference created for the HeNB cell by the necessity of the mobile user having to transmit and receive communications from a distant public macro eNB.

The FL interference between the macro cell and the HeNBs is also mitigated.
