Title: Logarithmic amplifier
Inventor: HOLDENRIED CHRISTOPHER D
IPC: H04B10/17
Filed: 2002-05-17
Abstract: A parallel-summation logarithmic amplifier is described that uses a novel topology of cascaded and parallel amplifiers to achieve extremely high bandwidth. Included in the topology is a unique delay matching scheme for logarithmic amplifiers that is amenable to fabrication in integrated circuit form. The result is flat group delay over broad frequency ranges and different power levels. The resulting log amplifier is suitable for radar applications and for use in high data rate fiber-optic networks. Also described is a unique design process that yields a set of amplifier gains that closely approximate a logarithm. Also described is the novel idea of using a parallel feedback amplifier (PFA) in piecewise-approximate logarithmic amplifiers. This innovation allows for the design of broadband amplifiers with significantly different gains and similar phase characteristics, which is extremely useful when designing high-frequency logarithmic amplifiers.

Title: A packet scheduler and method therefor
Inventor: CUDAK MARK
IPC: H04L12/56
Filed: 2001-01-15
Abstract: This invention relates to a packet scheduler and method therefor and in particular a scheduler for a Code Division Multiple Access cellular mobile communication system. In packet base systems it is important to schedule transmissions of packets carefully in order to maximise the capacity of the system. The scheduler has means (235) for maintaining a list of packets for a cluster of cells. A packet is selected from this list and processed in means (237) for calculating an increase in receive power level at a target base station and at other base stations caused by transmitting a packet. The results are fed to means (239) for scheduling packets to a base station so that only packets which do not result in an accumulated receive power level exceeding a maximum receive power level at a based station are scheduled. The scheduler is in particular appropriate for third generation mobile communication systems.
