摘要： A brevity signaling module for a digital television (DTV) receiver enables the reception of emergency broadcast messages. The overlay signal received at the receiver front end is squared in a squaring loop, producing spectral lines at DC and twice the overlay signal frequency, or 2&ohgr;, where &ohgr;=2&pgr;f and f is the center frequency of the overlay signal. The squared signal is passed through a narrow band filter having a bandwidth sufficient to pass a spectrum containing a plurality of tones 2&ohgr;, 2&ohgr;1, 2&ohgr;2, . . . , 2&ohgr;n, where 2&ohgr;1, 22, . . . , 2&ohgr;n are different frequency tones assigned to different auxiliary functions. The detected tone is used by a control module to determine whether normal multipath processing should be performed or whether this processing should be suppressed and auxiliary functions performed, including turning on the DTV receiver power in order that an emergency broadcast message might be conveyed to persons in the vicinity of the DTV receiver.

摘要： A system for spread spectrum power line communications employs a harmonic modulation (HM) transmitter coupled to the power line for transmitting message bits to an HM receiver. The spread spectrum accommodates a plurality of HM transmitters simultaneously occupying the same bandwidth. The spectrum of HM, in a frequency range above 60 Hz but below the maximum frequency that will carry through a distribution transformer, is ideal in combating carrier synchronous noise since it can be interleaved with the noise harmonics and therefore be effectively spectrally disjoint with the synchronous noise process spectrum.

摘要： The condition and/or integrity of goods is monitored while in transit using a local area network of tracked assets. Autonomous electronic sensors are situated in proximity to the cargo being shipped. These sensors communicate with an asset tracking unit affixed to the container for the goods via a mutter mode transceiver. The tracking unit has the ability to relay the cargo sensor data to the central station on demand, on exception, or on a predetermined schedule established by the central station. Communication between the cargo sensors and the tracking unit may be one-way (i.e., sensor to tracking unit) or two-way. Multiple sensors may communicate with each tracking unit.

摘要： DTV broadcast transmission is provided with a ultra wideband overlay signal which is used by suitably equipped DTV receivers to dynamically estimate the channel and allow expeditious and effective mitigation of changing multipath conditions. Periodic correlation peaks are detected in the received overlay signal, and the timing and magnitude of other peaks in the received overlay signal are used to mitigate multipath in the received signal. A DTV receiver that is not equipped to process the overlay transmission will not be significantly affected by the overlay signal.

摘要： Circuits are provided for transmitted reference spread spectrum systems using a noise-like digital sequence with delayed replica. The circuits produce the digital spreading sequences at extremely high speed, and are capable of providing a great degree of signal spreading. A first embodiment is composed of a low speed section and a high-speed section. This embodiment allows for greater power efficiency without sacrificing sequence speed. In addition, the embodiment also allows shaping of the spectrum of the high-speed digital sequence. Further, this embodiment generates an m-sequence and its near delay by storing decimated pieces of the entire m-sequence over a plurality of end-around circulating shift registers or so-called ring counters. The ring counters can be run at low speed and there is no exclusive-oring operation. A time-delayed transmitted reference spread spectrum transmitter is provided using digital noise generators that are capable of very high speed operation.

摘要： An ultra-wideband (UWB) communications system combines the techniques of a transmitted reference (TR) and a multiple access scheme called delay hopping (DH). Combining these two techniques using UWB signaling using a continuous noise transmitted waveform avoids the synchronization difficulties associated with conventional approaches. This TR technique is combined with the DH multiple access technique to create a UWB communications scheme that has a greater multiple access capacity than does the UWB TR technique by itself.

摘要： Reduction in the time required for an Advanced Television Standards Committee (ATSC) digital television tuner to equalize, converge, and acquire a digital television signal suitable for viewing, wherein early model ATSC tuners also include a National Television Standards Committee (NTSC) analog tuner, is achieved by using a microprocessor to control use of the NTSC tuner to scan television channels. A channel measurement module converts the scanned analog signal to a digital signal, and the equalization coefficients for the resultant digital signal are stored in memory. The equalization coefficients stored in memory are then accessed and utilized to tune in new channels on the ATSC tuner. The amount of time necessary for the ATSC tuner to tune in a new channel is thus reduced. When the ATSC tuner is in use, the equalization coefficient data stored in memory are periodically updated.
