Title: AGC scheme using characteristics of a received beacon signal particularly in a TDD-CDMA system
Inventor: ANDERSON NICHOLAS
IPC: H03G3/20
Filed: 2001-08-01
Abstract: Automatic gain control (AGC) and synchronisation acquisition by a communication unit in a wireless communication system, e.g. a TDD-CDMA system such as the Universal Mobile Telecommunication System (UMTS) system, is described. AGC is performed using a downlink beacon function, for example a power level (P<SB>beacon</SB>). Also disclosed is Amplitude-equalising (limiting) performed as part of synchronisation acquisition and the use of separate AGC processes for different stages of synchronisation acquisition. One AGC process uses a peak power (P(k)) of a received signal over a frame. Another AGC process uses a peak power (P(k)) of a received signal over only a portion of a frame, the portion comprising an initial synchronisation code. Another AGC process uses measurements of a received signal (P<SB>0</SB>(k)) taken in a downlink beacon timeslot. These processes tend to provide tolerance to a varying number of codes (M) transmitted on a timeslot-by-timeslot basis and robust initial synchronisation in the presence of strong uplink interference.

Title: Amplitude spectra estimation
Inventor: STARR JOEL
IPC: G01V1/36
Filed: 2000-07-07
Abstract: A method and system of amplitude spectra estimation for seismic data using up-going and down-going wavefields includes gathering up-going and down-going wavefields, separating the up-going and the down-going wavefields from each other and crosscorelating the up-going wavefields and the down-going wavefields. From the result of the crosscorrelation of the up-going wavefields and the down-going wavefields, an estimate of the amplitude spectra in the frequency domain of the seismic data can be obtained. In this method for amplitude spectra estimation, the gathering may include or may be accomplished by providing pressure and particle velocity detectors to distinguish between the up-going and the down-going wavefields. Also, in this method for amplitude spectra estimation, the gathering may include measuring the down-going waves and the separating may include removing the down-going waves from the seismic data. In the alternative, this method for amplitude spectra estimation, the gathering may include measuring the up-going waves and the separating may include removing the up-going waves from the seismic data.
