摘要： An Advanced Television Standards Committee (ATSC)-compliant pilot tone is generated within an 8-VSB (eight level vestigial sideband) transmission in order to enable Quadrature Amplitude Modulation (QAM) receiver designs to more efficiently process the transmitted/received 8-VSB signal. The method and apparatus also efficiently removes the pilot tone before using conventional QAM demodulator equipment for directly demodulating the 8-VSB signal.

摘要： An N-VSB (vestigial sideband) modulation signal is converted into an M-QAM (quadrature amplitude modulation) signal, where M=N2, by shifting the symbol rate frequency of a received N-VSB modulation signal to center the waveform spectrum about zero Hertz prior to complex demodulation so that data symbols will alternately appear on demodulated I and Q channels. A pilot tone of the received N-VSB modulation signal is removed to eliminate any bias in the both I and Q channels. Symbol timing between I and Q channels is offset, and quadrature amplitude demodulation of the I and Q channel signals generate alternating I and Q channel data symbols. Alternating inversion of the alternating I and Q channel data symbols recovers the N-VSB symbol data.

摘要： A system for communicating digital information over wires having a great deal of harmonic distortion, such as a power line, employs a transmitter which transmitter which creates a carrier wave for each of a plurality of signals to be sent. This carrier wave has frequency lobes positioned between the frequency lobes of the harmonic distortion. Each of the lobes of a single carrier signal is encoded with the same bit value during a given bit period. This signal is then mixed with any existing signal on the wire. At a remote receiver coupled to the wires, the signal is sensed, filtered, and Fourier transformed into coefficients. The signal-to-noise (S/N) ratio of each Fourier coefficient is determined by a novel S/N estimation technique. The coefficients are weighted based upon the S/N ratio estimation, and decoded, preferably by an inner product of the weighted Fourier coefficients. Additionally, the S/N ratio estimates could be time averaged before being used in the weighting and bit decoding.

摘要： A system and method for gathering diagnostic information relating to an operating condition of a gas stream or processing path of a coal gasification system is disclosed. The information is gathered by deploying one or more specially constructed modules or seeds that proceed through the gas stream of the coal gasification system as part of the mass flow of the gas stream. The seed may be physically recoverable in which an outer material of the seed ablates when exposed to a predetermined temperature of the gas stream. The seed may be physically non-recoverable in which electronic circuitry transmits a signal to a receiver relating to the temperature of the gas stream.
