摘要： A system and method for orthogonal time frequency space communication and waveform generation compatible with OFDM. The method includes receiving a plurality of information symbols and encoding an NxM array containing the plurality of information symbols into a two-dimensional array of modulation symbols by spreading each of the plurality of information symbols with respect to both time and frequency. The two-dimensional array of modulation symbols is then transmitted along with one or more OFDM symbols using a plurality of narrowband subcarriers.

摘要： Circuitry and methods for regulating alternating current regulation uses energy storage and release principles to boost or buck voltage to permit regulated ac operation with parallel and series bi-directional switch elements (12) and (13) operated at either variable duty cycles or frequencies to accommodate bipolar ac operation. Each bi-directional switch element may include a diode bridge (8) or (10) and directionally limited switches such as semiconductor switches. The system can be used to regulate ac even during sub-cycle dips, can be used to simulate controlled dips, can be used to correct power factor for loads, and can be applied in multiphase operations.

摘要： A current limiting method and apparatus for preventing fault overload in a utility power transmission system (10) employs a high power, superconducting coil based pulse transformer (36) for saturating the core of the utility power transformer (30) thereby limiting its current carrying capacity. The utility transformer core (54) is biased to a disadvantageous portion of its B-H curve. A fault condition is detected and as a result the superconducting coil (48) is quenched thereby sending a high energy pulse of current into the utility transformer magnetic core (54). The core, while heating, does not exceed its capability to maintain a stable thermal condition while at the same time limiting the current being transformed from its input (32) to output (34) lines, until a transformer circuit breaker activates.

摘要： A load is supplied by transformer 10 supplied via a voltage regulator and thyristor network. The thyristor network and regulator are simultaneously controlled to respond to changes in the load and in practice the thyristors respond rapidly and are re-adjusted as the regulator is inherently more slowly adjusted. The result is that the thyristors produce minimum reflected harmonics overall in the mains and an optimum power factor can be achieved for each power setting.
