Publication number: 20100272155Abstract: A code transmitted in a wireless format is to be detected. A power level associated with the code is determined. The determined power level is compared with a plurality of thresholds. A test statistic is increased or decreased based on which of the thresholds that the determined power level falls within. If the test statistic exceeds an acceptance threshold, the code is deemed acquired. If the test statistic is below a dismissal threshold, the code is deemed not present. If the test statistic does not exceed the acceptance threshold and the test statistic is not below the dismissal threshold, the testing for the code is repeated.Type: ApplicationFiled: July 8, 2010Publication date: October 28, 2010Applicant: INTERDIGITAL TECHNOLOGY CORPORATIONInventors: Gary Lomp, Fatih Ozluturk, Avi Silverberg

Patent number: 7085255Abstract: In a TDD wireless communication system between transmitters and associated receivers, automatic gain control of a receiver is only applied during the corresponding time slot within the TDD signal time frame architecture. Successive received signal strengths are measured and gain levels are stored as estimates for an initial gain level in future time slots of the TDD signal. Estimating techniques, such as averaging or trending of received signal strength over successive time slots, and averaging or trending of gain level settings, provide improved estimation of future initial gain levels.Type: GrantFiled: June 1, 2001Date of Patent: August 1, 2006Assignee: InterDigital Technology CorporationInventors: Alexander Jacques, Leonid Kazakevich, Avi Silverberg

Patent number: 6985467Abstract: A method and system for rapidly acquiring a spreading code, used in a code division multiple access (CDMA) system. A first long code and a second long code, with each long code having a length of N chips, are generated. The first long code is different from the second long code. The first long code and the second long code are transmitted at a first phase angle and at a second phase angle, respectively, on a carrier signal, over a communications channel using radio waves. The first long code and the second long code may be transmitted at an in-phase (I) angle and at a quadrature-phase (Q) angle, respectively, on the carrier signal. From the communications channel, an I-phase acquisition circuit and a Q-phase acquisition circuit may acquire, in parallel, the first long code and the second long code from the I-phase angle and the Q-phase angle, respectively, of the carrier signal by searching, in parallel, N/2 chips, the first long code and the second long code.Type: GrantFiled: January 10, 2001Date of Patent: January 10, 2006Assignee: InterDigital Technology CorporationInventors: Gary Lomp, John Kowalski, Fatih Ozluturk, Avi Silverberg, Robert Regis, Michael Luddy, Alexander Marra, Alexander Jacques

Patent number: 6831905Abstract: A spread spectrum system having an assignor, a spread-spectrum processor and a transmitter. The assignor assigns each arriving information signal to a message-code signal. Each message-code signal is different then other message-code signals. The spread-spectrum processor generates a pilot code signal and processes the information signals with the message-code signals to generate spread-spectrum process-message signals synchronized to the pilot-code signal. A transmitter combines the spread-spectrum process-message signals and the pilot-code signal to generate a CDM signal. The transmitter modulates the CDM signal with a carrier signal for transmission over the communications channel.Type: GrantFiled: August 9, 2000Date of Patent: December 14, 2004Assignee: InterDigital Technology CorporationInventors: Gary Lomp, John Kowalski, Fatih Ozluturk, Avi Silverberg, Robert Regis, Michael Luddy, Alexander Marra, Alexander Jacques

Patent number: 6801516Abstract: A spread-spectrum system having an assignor, a spread-spectrum processor, a call processor, and an information-channel-mode modifier. The assignor assigns each information signal arriving at the spread-spectrum system to a message-code signal. Each of the message-code signals supports a pre-determined information-channel rate. Several information signals have different channel rates, and each information signal is assigned according to the required channel rate. The spread-spectrum processor generates a pilot-code signal, and spread-spectrum processes the information signals with the message-code signals to generate a plurality of spread-spectrum processed-message signals, respectively. The message-code signals are synchronized to the pilot-code signal. The call processor provides a call-type signal corresponding to the information signal rate for the several information signals having several different channel rates.Type: GrantFiled: August 9, 2000Date of Patent: October 5, 2004Assignee: InterDigital Technology CorporationInventors: Gary Lomp, John Kowalski, Fatih Ozluturk, Avi Silverberg, Robert Regis, Michael Luddy, Alexander Marra, Alexander Jacques
