Abstract: PURPOSE: An apparatus is provided for determining frequency offsets caused by oscillator error or Doppler effects in a user terminal in a communication system. CONSTITUTION: A system (100) includes at least one user terminal (124, 126) and a base station (112), or gateway (120, 122) for communicating through a satellite (116, 118) with predetermined orbital positions or patterns. A communication signal (500) is precorrected (512) for known Doppler effects, such as between a gateway and a transferring satellite, when used, and transmitted to a user terminal. The user terminal determines the signal frequency relative to a reference oscillator (516, 518), and treats any detected difference as resulting completely from Doppler. The frequency difference is either transferred as data in reverse link transmissions (524, 526), or used as a pre-correction factor for such transmissions (522, 526). The frequency of the reverse link user terminal signals is measured at the gateway (528), again compensating for knowm Doppler effects, to provide a nominal error measurement (530). Measured frequency error or offsets are then divided in half to arrive at a Doppler shift error, or divided in half and scaled to the appropriate frequency to arrive at a user terminal oscillator error (532).The detected error can be transmitted to the user terminal (534) for use in correcting the oscillator output frequency, or for adjusting the timing of, or time tracking for, the user terminal. Alternatively, the detected error can be included as data in subsequent signals for use by gateways or base stations (538, 540).

Title: Method of operating the channel equalizer in a receiver for dtv signals subject to co-channel ntsc interference
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-09-18
Abstract: PURPOSE: A method of operating a channel equalizer in a receiver for digital television signals subject to co-channel interference from analog television signals is proposed to avoid the initialization of the filter coefficients of the adaptive channel equalization filter in response to training signal being affected by artifacts of co-channel NTSC interference that accompany the DFS signals. CONSTITUTION: The DTV signal receiver includes an adaptive channel equalization filter, a comb filter(20) for suppressing artifacts of co-channel NTSC interference, and an intersymbol-interference suppression filter(26) compensating for the intersymbol interference introduced by the comb filter(20). The adaptation of the equalization filter coefficients is done so as to be insensitive to the presence or absence of the artifacts of co-channel NTSC interference. This avoids the channel equalization filter attempting to compensate for the intersymbol interference introduced by the comb filter(20), which compensation could not be fully accomplished and would make the intersymbol interference in the comb filter(20) unpredictable. The adaptation of the equalization filter coefficients is done so as not to affect the intersymbol interference introduced by the comb filter(20). Consequently, the intersymbol interference can be properly compensated for by the intersymbol-interference suppression filter(26).
