摘要： 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.

摘要： 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.

摘要： The invention is directed to efficient transfer of low bit rate services in a communication system. A synchronization symbol which has known characteristics may be included as a first symbol of digital broadcast frames. The synchronization symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. Low bit rate services are allocated to time slots following the pilot symbol used for synchronization allowing for fast access times with maximum power saving capabilities. A user terminal wakes up just before the synchronization symbol and received the data allocated for the low bit rate services. The user terminal may power off for the remaining time slots which are allocated for higher bit services to conserve power.

摘要： Aspects of the invention are directed to service and channel discovery in a digital broadcast network. A pilot synchronization symbol, which has known characteristics, is included as a first symbol of digital broadcast frames. The pilot symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. So, the rest of the signal can be decoded without trial and error methods after the pilot symbol (and any additional synchronization symbols) is decoded. Channels containing digital video broadcast services can be efficiently detected using the known part of the signal. If the fixed known part is not found from the examined signal, then the signal will be considered a non-digital-video-broadcast signal or an empty channel, and the receiver can promptly proceed to a next channel/frequency. In this way, detecting non-digital-video-broadcast and empty channels becomes relatively fast.
