Abstract: Apparatus and methods of implementing code space search of received signals are described herein. A code space search is implemented as a searcher that perform a subtask that is dynamically reconfigurable at each boundary of an initial integration time. Each particular subtask sets forth a programmable configuration of coherent integration hypothesis that are performed during the initial integration time. The searcher stores the results of the coherent integration hypothesis in a first portion of memory. A search accelerator operates on the initial integration results. The search accelerator can perform coherent integration of various frequency bins of different timing hypothesis, can generate energy values of the coherent integration results, and can generate a non-coherent energy summation. The energy values of the coherent integrations and non-coherent energy summations are stored in a second portion of memory. The ability to reconfigure the subtasks and accelerator operation provides flexibility in search space dimensions.

Abstract: A network synchronization method designed to provide synchronization of multiple networks and devices. This invention provides a specific method for determining which nodes are responsible for network synchronization as nodes fail or cannot see each other due to conditions on the network. This allows for fault tolerance in a network in which conditions change dynamically. In addition, this invention uses synchronization codes and network numbers to isolate separate networks using the same physical medium, thus allowing sharing of network resources.

Abstract: A method for reducing call dropping rates in a multi-beam communication system. The multi-beam communication system includes a user terminal, a gateway, and a plurality of beam sources, where each beam source projects a plurality of beams, and where a communication link between the user terminal and the gateway is established on one or more beams. The method according to the present invention relies on a messaging protocol between the gateway and the user terminal. Based on messages sent from the user terminal to the gateway, preferably on a preselected periodic basis, the gateway can determine the more desirable beam(s) for transmitting data or information to the user terminal. The messages sent from the user terminal to the gateway contain values representing beam strengths as measured at the user terminal. The gateway uses the user terminal measured beam strengths to select the beams that should be used for transmitting data or information to the user terminal. The beams that should be used are the beams that if used will decrease the call dropping rates and provide a desired level of beam source diversity.
