摘要： Methods and apparatus for iterative timing recovery are provided that can be used, for example, in phase shift keying systems. The methods include processing an input signal using an FEC decoder, using some of the information from the FEC decoding process to estimate the phase of the symbol carrier, and correcting the phase for subsequent input signals. Another of the embodiments under the present principles provides for post-processing of the phase estimation prior to using the estimate for phase correction. Another embodiment is a post processor that comprises a filter, including a Kalman filter. Another embodiment includes using a priori information embedded in the input signal, such as a synchronization signal, to assist the phase estimation process.

摘要： Efficient and reliable FEC frame header improvements suitable for headers for data packets in a digital cable television transmission system are provided. In one embodiment, the DVB-C2 Standard, Adaptive Coding and Modulation (ACM) or Variable Coding and Modulation (VCM) is applied to each FEC block to provide as much flexibility as possible. As a result, a frame header is attached in front of each FEC frame to inform the coding rate, modulation type and physical layer pipe identifier. Besides the signaling of physical layer related information, the FEC frame header has to provide a structure so that it can be easily and reliably detected in the receiver. A frame header for Forward Error Correction (FEC) encoded frames is designed for use in the DVB-C2 Standard with an extra bit to convey additional information. The FEC frame block can also include the FEC header for the subsequent FEC data block to increase robustness. The power level of the FEC header can also be increased relative to the data portion. Different modulation methods can be used for the FEC frame header depending on the modulation method used for the FEC frame data portion. These techniques increase the flexibility and robustness of FEC header detection.
摘要翻译：提供了适用于数字有线电视传输系统中的数据分组头部的高效可靠的FEC帧头改进。在一个实施例中，将DVB-C2标准，自适应编码和调制（ACM）或可变编码和调制（VCM）应用于每个FEC块以提供尽可能多的灵活性。结果，在每个FEC帧的前面附加帧头，以通知编码率，调制类型和物理层管道标识符。除了物理层相关信息的信令之外，FEC帧报头必须提供一种可以在接收机中容易且可靠地检测的结构。用于前向纠错（FEC）编码帧的帧头被设计用于具有额外位的DVB-C2标准以传送附加信息。 FEC帧块还可以包括用于后续FEC数据块的FEC报头以增加鲁棒性。也可以相对于数据部分增加FEC报头的功率级。根据用于FEC帧数据部分的调制方法，不同的调制方法可用于FEC帧报头。这些技术增加了FEC报头检测的灵活性和鲁棒性。

摘要： A system/method is shown for reusing digital video broadcasting for satellite, second generation (DVB-S2), low-density parity check (LDPC) codes, and hence also DVB-S2 hardware, in digital video broadcasting for cable, second generation (DVB-C2) contexts. LDPC codes are susceptible to an error threshold, beyond which the coded information cannot be accurately retrieved. By matching the varying levels of protection within an LDPC codeword with the varying levels of protection in quadrature amplitude modulation, the number of errors can be kept below the error threshold.
