Patent number: 6356607Abstract: In a first embodiment of the invention, a concatenated preamble code is formed by a kronecker product between two subcodes of the same or different lengths. The subcodes have favorable correlation properties and may be Barker codes, minimum peak sidelobe codes, Gold codes, Kasami codes, Bozta codes, or other codes. At the receiver a two-stage processor is used to detect the concatenated preamble code. The two-stage processor comprises a series of two filters, one of which is preferably a mismatched filter. In another aspect of the invention, a repeated codeword preamble is formed from a series of the same repeated short subcode. The short subcode may be an augmented or truncated odd-length code. At the receiver a single matched filter is preferably used to generate a series of spikes separated by the period of the subcode. An alert/confirm detector non-coherently adds together individual correlation spikes and reject false alarms.Type: GrantFiled: November 15, 1996Date of Patent: March 12, 2002Assignee: Omnipoint CorporationInventors: Logan Scott, Robert Monroe

Patent number: 6282228Abstract: A technique for modulating and demodulating CPM spread spectrum signals and variations of CPM spread spectrum signals uses a set of codes or multiple sets of codes that reduce cross-correlation interference. A transmitter divides a signal data stream into I and Q data streams, independently modulates the I and Q data streams using CPM or a related technique, and superposes the plurality of resultants for transmission. A receiver receives the superposed spread spectrum signal, simultaneously attempts to correlate for I and Q chip sequences, and interleaves the correlated I and Q data streams into a unified signal data stream. In one embodiment the receiver separates the received spread spectrum signal into real and imaginary parts, attempts to correlate both real and imaginary parts for a plurality of chip sequences, and combines separate correlation signals into a unified signal data stream.Type: GrantFiled: March 20, 1997Date of Patent: August 28, 2001Assignee: Xircom, Inc.Inventor: Robert Monroe

Patent number: 6150714Abstract: An electronic device includes a conductive member disposed within an insulative package. The conductive member is formed from a lead frame used to form the interconnection pins for the device. The conductive member includes an elongated, folded sense element portion having a known resistance. The sense element portion is disposed between two sets of conductive lead portions extending from the conductive member forming pins used to provide a current to the device for sensing. An integrated circuit disposed within the package includes a differential amplifier having differential inputs connected to bond pads on the integrated circuit. The bond pads are connected to spaced-apart tap points of the sense element via conductive bond wires, so that the combination of the sense element and the differential amplifier forms a trans-impedance amplifier. The gain of the differential amplifier is controlled to be proportional to the magnitude of a reference voltage generated by a bandgap voltage reference circuit.Type: GrantFiled: September 18, 1998Date of Patent: November 21, 2000Assignee: Texas Instruments IncorporatedInventors: William M.
