    • Aspects of the invention are directed to a cell-frequency-link descriptor configured to map network-specific parameters with time frequency slicing (TFS) information in a digital video broadcast system. The cell-frequency-link descriptor may include fields that provide a mapping between a cell identifier, a TFS group identifier, a bandwidth, a guard interval, a transmission mode, and a frequency. The fields may provide a mapping between cells, frequencies, TFS groups, related guard intervals, bandwidths, and transmission modes for multiple cells within the digital video broadcast system. The fields may include: a cell identifier field, a TFS-group identifier field, a bandwidth field, a guard interval field, a transmission mode field, a frequency field, a cell identifier extension field, and a transposer frequency field.

    • Embodiments are directed to binary phase shift key modulating a first pilot symbol according to a reference sequence, and differentially binary phase shift key modulating a second pilot symbols. The original reference sequence and the delayed differentially modulated sequence are then combined before performing an Inverse Fast Fourier Transform and inserting a guard interval. Receiver operations are an inverse of the transmitter operations, which were just discussed. The receiver does not have to know the reference sequence. Embodiments are directed to specifying a plurality of seeds that are bit patterns each having r bits not all of which have a value of zero, extending the seeds into respective sequences by applying to each seed a recurrence formula; and using one of the sequences as a comb sequence and using the sequences other than the comb sequence as binary phase shift keying patterns.
    • 实施例涉及根据参考序列调制第一导频符号的二进制相移键,以及调制第二导频符号的差分二进制相移键。 然后在执行快速傅立叶逆变换和插入保护间隔之前组合原始参考序列和延迟差分调制序列。 接收机操作是发射机操作的倒数,这些操作刚刚讨论过。 接收器不必知道参考序列。 实施例涉及指定多个种子,其是每个具有r位的位模式,并不都具有零值,通过向每个种子应用递归公式将种子延伸到各个序列中; 并使用序列之一作为梳状序列,并使用除了梳状序列以外的序列作为二进制相移键控模式。

    • Elements of a coding table which are error-free are found at S2. At S3, corresponding elements in an erasure information table are completed, indicating that the elements in the coding array are correct. A counter is initialized at Nmax, which is the maximum number of errors that can be corrected, at S4. At S5, the row of the erasure information table is scanned beginning from the first parity column for empty elements. Each empty parity date element of the erasure information table row is marked as incorrect at S7 For each such element, the counter is decremented at S8. At S9, the elements of the erasure information table are scanned from the first column of the application data and zero padding section for empty elements. At step S11, an empty element is marked as incorrect. At step S12, the counter is then decremented. It is determined at step S13 whether or not the counter is equal to zero. When the counter becomes is equal to zero, operation proceeds to step S14 where the decoder operates to fill remaining empty elements in the erasure information row as correct. Thus, whilst the count of incorrect elements for the row has not exceeded a maximum and whilst empty elements remain, empty elements of the erasure table row are marked as incorrect beginning with parity data elements and then continuing from the application data end.
    • 在S2中找到无错误的编码表的元素。 在S3,擦除信息表中的相应元素完成,指示编码数组中的元素是正确的。 在S4处,计数器被初始化为Nmax,其是可以校正的最大错误数。 在S5,从空白元素的第一奇偶校验列开始扫描擦除信息表的行。 擦除信息表行的每个空的奇偶校验日期元素在S7中被标记为不正确对于每个这样的元件,在S8处计数器递减。 在S9中,从应用数据的第一列和空元素的零填充部分扫描擦除信息表的元素。 在步骤S11中,空元素被标记为不正确。 在步骤S12,计数器然后递减。 在步骤S13中确定计数器是否等于零。 当计数器变为零时,操作进行到步骤S14,其中解码器操作以填充擦除信息行中的剩余空元素作为正确的。 因此,虽然该行的不正确的元素的计数没有超过最大值,而当剩余空元素时,擦除表行的空元素被标记为不正确,从奇偶校验数据元素开始,然后从应用数据结束继续。
