    Abstract: A first group of embodiments is 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 symbol. 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. The receiver does not have to know the reference sequence. A second group of embodiments is 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, 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: Embodiments are directed to first and second OFDM pilot symbols. The first and second pilot symbols may have first and second sets, respectively, of allowed, forbidden, and active carrier frequencies. The second sets of carrier frequencies may be formed by frequency shifting the respective first sets by a predetermined frequency, such as the frequency difference between adjacent carriers. An embodiment 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: A communication system may include a single frequency network or cell having multiple transmitting apparatuses, configured to transmit a data stream to receiving devices within respective coverage areas. The data stream may include a series of frames having preambles that indicate whether the transmitting apparatus from which it is transmitted is located in a border region towards the edge of its cell. A receiving apparatus that experiences deterioration in the signal received from a transmitter can use the indication in the preamble to determine whether to start preparations for a handover to a transmitting apparatus in a neighbouring single frequency network. In this manner, the receiving apparatus can distinguish between a potential handover situation and a temporary deterioration in the received signal from other factors, such as interference and unnecessary handover preparations may be avoided.

    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. The receiver performs a process involving phase demodulating at least one signal part of each of the received data symbols, phase remodulating the demodulated symbols, and performing a correlation of the received symbols with the reference sequence to permit decoding of the data stream.

    Abstract: Aspects of the invention provide apparatuses, computer media, and methods for supporting the broadcast of extended signaling data over a network. With an aspect of the invention, all of the extended signaling data may be distributed over multiple data frames. With another aspect, only dynamic signaling redundancy data is distributed over different data frames, where systematic information (for example, configurable signaling data) is transmitted in accordance with traditional systems. In addition, backwards compatibility with traditional systems may be supported, in which extended signaling is contained in an extension field. Error correction code may be applied to the extended signaling in concert with different codes. With another aspect, only extended signaling is supported without backwards compatibility with traditional systems.
