Abstract: Embodiments are directed to first and second OFDM pilot symbols. The first and second pilot symbols have first and second sets, respectively, of allowed, forbidden, and active carrier frequencies. The second sets of carrier frequencies are formed by frequency shifting the respective first sets by a predetermined frequency. A receiving method is directed to frequency translating part of a first received pilot symbol by one carrier interval in a first direction, frequency translating part of a second received pilot symbol by one carrier interval in a second direction that is opposite from the first direction, and forming a correlation by multiplying the frequency translated parts of the first and second pilot symbols by complex conjugates of parts of the pilot symbols upon which frequency translation has not been performed, and summing the multiplication results.

Abstract: 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.

Abstract: Partial data streams are included in the same physical layer pipe over a communications channel in accordance with different modulation schemes and code rates. Consequently, a receiver can extract the first and second partial data streams from the same physical layer pipe of a signal received on the communications channels based on the associated signaling information, where each partial data stream may be associated with a physical layer pipe component. Before transmission, cells from different physical layer pipe components are multiplexed to form a combined data stream. The ordering of cells within the combined data stream may then be permuted so that different mappings of the physical layer pipe components to carriers in many consecutive orthogonal frequency division multiplexing symbols may be insured. Signaling information may included in the transmitted data stream so that a receiver can extract information from the physical layer pipe components in accordance with the related modulation schemes and code rates of each physical layer pipe component.

Abstract: An apparatus comprises a sequence generator configured to generate a reference sequence for scrambling scattered pilots, edge pilots and/or frame closing pilots in data symbols, such as Orthogonal Frequency Division Multiplexing (OFDM) symbols in a data stream. The sequence is based, at least in part, on a symbol number of the data symbol in which the pilots are to be included. A receiving apparatus may then identify a symbol having a particular symbol number in a received data stream based on the scrambling sequence. Where the data stream carries multiple services in bursts or time slices, the receiving apparatus may remain in sleep mode between the bursts associated with a desired service. The method permits a receiver that has "woken up" to identify a received symbol having a particular symbol number and synchronize its symbol index.

Abstract: A digital video broadcasting (DVB) receiver processes baseband (BB) frames at both a basebase (BB) block level and a terminal block level. At the BB block, the DVB receiver synchronizes BB frames from synchronization information inserted in the BB frame headers. The BB block configures the error indicator based on whether an error is detected in the BB frame. The DVB receiver also processes signaling information in the preamble of the T2 physical layer frame only if indicated by the signal changed field. The BB passes the processed BB frame to the terminal block of the DVB receiver for processing network packets that is contained in the BB frame. A DVB transmitter inserts a synchronization field and payload type field in the BB frame header of the BB frame and also determines 10 whether there has been a change in the signaling information at the physical layer and configures the signaling changed indicator accordingly.

Abstract: Systems and methods for receiving an OFDM preamble without knowledge of channel characteristics are provided. An OFDM preamble signal with frequency shifted cyclic extensions is received. Taken together the cyclic extensions form a frequency shifted version of the OFDM preamble signal. Frequency offsets and timing offsets are estimated and corrected in an efficient manner using a simple concatenation approach in the time domain, followed by a summation of the OFDM preamble signal and the concatenation after a transformation of the OFDM preamble and the concatenation into the frequency domain. Phase errors in the frequency domain are estimated and corrected after FFT transformations of the received signals. A valid preamble is detected and additional parameters for receiving subsequently transmitted OFDM symbols in a channel are extracted from the OFDM preamble. The methods are computationally efficient and robust. Receiver implementations for performing the methods in a DVB receiver are disclosed.
