摘要： The current application is directed to maintaining the correct number of symbols in a protocol frame in a digital communications receiver, to prevent catastrophic failure due to dynamic multipath or cycle slips. Timing recovery and framing are coherent, facilitated by placing channel estimation directly into a larger timing recovery loop.

摘要： The present invention is related to channel identification, equalizer initialization, and framing synchronization of GB 20600-2006 digital television signals. In one embodiment, the present invention provides, in a communications receiver having an equalizer that processes GB 20600-2006 digital television signals that include payload data, a method that initializes the equalizer coefficients for processing the payload data comprising: identifying a channel estimate based on correlation techniques; producing known, mock received data and filtering the mock, received data through the channel estimate to produce mock filtered data; adjusting the equalizer coefficients with the mock received data or the mock filtered data to obtain an initial equalizer setting; and processing the payload data with the initial equalizer setting.
