摘要： A system and method for enabling voice and broadband data delivery to users in expeditionary deployments is disclosed. More specifically the system is composed of a registration server, a wireless telco network server, a wide area transport network, and an external network interconnect (like satellite or fiber location) such that when users arrive at a disaster scene where communications infrastructure has been destroyed or is unavailable, they are either handed a smart device (smartphone, laptop, tablet, etc.) or they utilize an existing smart device they brought with them (BYOD) and via the Wi-Fi interface they connect to the wide area transport network.

摘要： A MIMO antenna used in both transmit and receive operations, with the ability to serve an n-by-n MIMO transceiver architecture (where n can take integer values between 0 to 4). The structure is designed to increase the effective area of the array by coupling the bars of the antenna to the disc and results in good isolation and low envelope correlation.

摘要： An IP packet transmission system is disclosed and more specifically it is a system using a hybrid ARQ method including a sliding purge window and having the transmitter opportunistically piggy-back a snapshot of the transmitter's transmit/send window in data frames. When the receiver receives this snapshot the receiver can compare it with its receive window and if a mismatch is detected, whereby the transmitter has moved on to the next packet, the receiver can now also sync up quicker and not wait for the regular timeout to progress ahead.

摘要： A cognitive radio signal processing method suitable for single receiver devices where interference is mitigated using projection of received multi-dimensional signal space to maximize SNR by orthogonalizing interference is described. The method is based on a well-known LMS solution that is computed from received multi antenna and multicarrier signals in a novel way. This method solves the requirement of multiple RF chains in low cost handsets by introducing a protocol synchronous antenna switcher that allows, for example, a LTE handset with a single antenna to benefit from algorithms that typically require multiple receivers for the same frequency, i.e. MIMO.
