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： A proposal for a DVB-C2 baseline system, mainly focused on the channel coding and bit interleaving modules for spectrally efficient modulation is described. Due to the implementation simplicity of the low density parity check (LDPC) codes standardized in the DVB-S2 specification, it is proposed to extend their application to cable channels and choose the subset with long block length ( L = 64800 ) and medium to high rates ( 2/5 ≤ R ≤ 9/10 ) as the forward error correction (FEC) codes of DVB-C2 systems. Due to the non-uniform bitwise error protection inherent to high-order modulations (e.g. 256-QAM, 1024-QAM) and irregular LDPC codes (e.g. DVB-S2 codes), there exists a mismatch between the modulation and the channel coding in general if the two modules are developed independently but concatenated directly. To match the error resilience of a finite-length channel code and a given constellation, the principles described herein design a bit interleaver and insert it between the channel encoder and the modulator. As a result, a better tradeoff between bandwidth-efficiency and power-efficiency can be achieved with a minor increase of hardware complexity.
摘要翻译：描述了主要关注用于频谱高效调制的信道编码和比特交织模块的DVB-C2基线系统的提议。由于在DVB-S2规范中标准化的低密度奇偶校验（LDPC）码的实现简单性，提出将其应用扩展到有线信道，并选择长块长度（L = 64800）和中到高的子集速率（2/5 = R = 9/10）作为DVB-C2系统的前向纠错（FEC）码。由于高阶调制（例如256-QAM，1024-QAM）和不规则LDPC码（例如DVB-S2代码）固有的不均匀的逐位错误保护，一般在调制和信道编码之间存在不匹配如果两个模块是独立开发的，但是直接连接。为了匹配有限长度信道码和给定星座的错误弹性，本文描述的原理设计了一个比特交织器，并将其插入到信道编码器和调制器之间。因此，可以通过轻微增加硬件复杂性来实现带宽效率和功率效率之间更好的权衡。

摘要： A method and apparatus for identifying valid multipath energy peaks are described including locating an energy peak in a profile of energy peaks, categorizing the located energy peak based on a plurality of thresholds and processing energy peaks in at least one of the categories of located energy peaks. The method and apparatus further includes removing a direct current value component from each value in the profile of energy peaks, calculating a noise floor for a multipath searching window and determining a first threshold and a second threshold. The step and means for categorizing further includes determining if the located energy peak exceeds the first threshold, labeling the located energy peak as a false alarm, if the located energy peak does not exceed the first threshold, determining if the located energy peak exceeds the second threshold and labeling the located energy peak as confident, if the located energy peak exceeds the second threshold.

摘要： A satellite television ground system, particularly for a make or break satellite television signal system, includes an outdoor unit and an indoor unit that are in communication with each other via a single coaxial cable and an optional separate single conductor for power. The satellite television ground system is operative to measure and reverse frequency conversion errors utilizing DSP techniques, allowing for more precise generation and transmission of uplink signals from the satellite television ground system. Control data for the system is sent via a low data rate connection on a power cable thereof, or by a narrowband signaling channel via a coax cable. The system also utilizes a single reference oscillator to drive the various frequency synthesizers and the like. The satellite television ground system utilizes related oscillators for the uplink and downlink sections. Carrier frequency offset in the downlink is measured in a carrier tracking loop part of a television signal demodulator. The carrier frequency offset of the downlink is utilized to synthesize various frequency signals for the uplink and downlink sections to correct frequency errors. For the uplink section, the carrier frequency offset of the downlink is reversed in the uplink. If the uplink is on a different frequency, the measured offset of the system master oscillator can be scaled by different synthesizer ratios.

摘要： A method and apparatus for improving the reception of digitally modulated signals. A main signal (31) and a supplemental signal (21) are provided in the transmitter. The signals may be substantially identical except that the supplemental signal is advanced in time with respect to the main signal. The main and supplemental signals are sent from the transmitter to the receiver modulated on a signal. At the received, the supplemental signal is stored in a buffer. If the main signal is undesirably changed during transmission, corresponding portions of the supplement signal are substituted for the undesired portions of the main signal.
