Publication number: 20160204809Abstract: For small cells, transceivers demand high performance while maintaining system efficiency. The present disclosure describes a highly integrated cellular transceiver that offers such features by providing one or more digital functions on-chip, onto the same die in the cellular transceiver. Effectively, the scope and boundary of the cellular transceiver is expanded to move beyond the data converters of the transceiver to include a variety of digital functions, thus integrating more of the signal chain in the cellular transceiver. Integration can greatly reduce complexity for the baseband processing, lower the cost of the overall transceiver system, reduce power consumption, and at the same time, benefit from improvements on the digital functions through integration.Type: ApplicationFiled: December 18, 2015Publication date: July 14, 2016Applicant: ANALOG DEVICES GLOBALInventors: PATRICK PRATT, MARTIN STEVEN McCORMICK

Publication number: 20160094253Abstract: An approach to linearization relaxes the requirements on the digitization of the analog output signal while maintaining the benefits of a high sampling rate of the output signal. The digitization approach extracts sufficient information to characterize the output signal over a wide bandwidth without necessarily determining sufficient information to fully represent the output signal, for example, without sampling the output signal at the Nyquist sampling rate with a sufficient precision to accurately represent the signal.Type: ApplicationFiled: May 20, 2014Publication date: March 31, 2016Applicant: ANALOG DEVICES, INC.Inventors: THEOPHANE WEBER, MARTIN STEVEN McCORMICK, QINGDONG MENG

Patent number: 8406812Abstract: The invention provides an antenna array suitable for use in a base station in a wireless communications network, the antenna array having a first beamforming arrangement for producing uplink beams and a second beamforming arrangement for producing downlink beams, wherein the first and second beamforming arrangements are different from one another. Preferably the first and second beamforming arrangements feed a common antenna array to produce the uplink and downlink beams. Particularly preferably a plurality of (sin x/x) beams are formed for the uplink, and a plurality of low cusp beams are formed for the downlink. These are advantageously dual polar, in order to achieve diversity gain. In a preferred embodiment, the antenna array is arranged such that three dual polar low cusp beams are formed for the downlink, and six dual polar (sin x/x) beams are formed for the uplink.Type: GrantFiled: August 17, 2010Date of Patent: March 26, 2013Assignee: Apple, Inc.Inventors: Martin Stevens Smith, Andrew James Urquhart, Julius George Robson, David Damian Nichols Bevan

Publication number: 20110215960Abstract: A method of receiving signals from an aircraft transponder is provided that enables ADS-B signals to be decoded even though parts of the signal may be overlapped due to interference. A plurality of antennas are summed and subtracted in pairs in order to create directional signal channels, which are then assessed for the confidence of the signals received. Where a channel contains a section of the signal of low confidence, the signal from another channel may be substituted for that section.Type: ApplicationFiled: March 3, 2011Publication date: September 8, 2011Inventors: Michael Stevens, Martin Stevens

Patent number: 7719459Abstract: A method and apparatus for determining a value of each bit in a secondary radar response pulse train sampled at a bit rate greater than one sample per bit is provided. The received signal is sampled repeatedly over a bit period. A scale factor for a weighting function is defined based on the amplitude levels detected from the response preamble. The weighting function has a maximum positive value at the expected bit amplitude for the first half of the bit period and decays to zero at higher amplitudes so that the effect of very large samples will be negligible. For lower amplitudes, the weighting decays to zero at the threshold level and becomes increasingly negative until zero amplitude. In the second half of the bit period the sign of the weighting function is swapped compared to the first half. The amplitude samples taken during the bit period are then each applied to the weighting function and the sum of the weighting function for the samples taken over the bit period is calculated.Type: GrantFiled: March 7, 2005Date of Patent: May 18, 2010Assignee: Raytheon Systems LimitedInventors: Martin Stevens, Quenton Jones

Patent number: 7123200Abstract: A sea surface antenna comprises a cylindrical tube of metallic material 13 on a dielectric former. The tube has a longitudinal slot shorted at each end and coupled at its midpoint to a coaxial feed. The slot is bridged by two groups of capacitances each group being distributed along a respective half of the slot. The length of the antenna is less than 0.25 ? and the diameter of the antenna is less than 0.02 ?, where ? is the free space wavelength at the operating frequency. The antenna is dimensioned so as to operate in an evanescent mode at a resonant frequency less than the cut-off frequency.Type: GrantFiled: May 2, 1991Date of Patent: October 17, 2006Assignee: Nortel Networks LimitedInventors: Martin Stevens Smith, David Neil Adams
