Abstract: Изобретение относится к инженерным способам защиты окружающей среды и может быть использовано для рекультивации грунтов на заболоченной территории в зоне влияния нефтегазового комплекса. Способ водопонижения нефтезагрязненных грунтов, характеризуется тем, что на поверхности грунта бурят центральный колодец, от которого в радиальном направлении выкапывают траншеи и укладывают в них под уровень грунтовых вод перфорированные трубы, при этом грунтовые воды самостоятельно стекают в центральный колодец, расслаиваются на поверхностный слой нефтепродуктов и воду. Поверхностный слой нефтепродуктов откачивают насосом в накопитель, а воду откачивают на поверхность, подвергают очистке отстаиванием в двухсекционном отстойнике, далее последовательным фильтрованием в коалесцирующей, зернистой и сорбционной загрузке, далее обеззараживают ультрафиолетовым излучением и накапливают в резервуаре чистой воды, после чего очищенную грунтовую воду под напором подают в инфильтрационную нагнетательную скважину, расположенную вблизи источника водоснабжения. Осадок, извлеченный из отстойника, и грунт, извлеченный из колодца и траншей при строительстве, размещают на площадках биодеструкции нефтепродуктов. Технический результат состоит в обеспечении водопонижения и обезвреживания грунтовых вод, обеспечении обезвреживания извлеченных грунтов и осадков и утилизации очищенных грунтовых вод. 1 табл., 1 ил.

Title: Signal processing with channel eigen-decomposition and channel inversion for mimo systems
Inventor: KETCHUM JOHN W
IPC: H04B7/04
Filed: 2003-06-20
Abstract: Techniques for processing a data transmission at a transmitter and receiver, which use channel eigen-decomposition, channel inversion, and (optionally) "water-pouring". At the transmitter, (1) channel eigen-decomposition is performed to determine eigenmodes of a MGMO channel and to derive a first set of steering vectors, (2) channel inversion is performed to derive weights (e.g., one set for each eigenmode) used to minimize ISI distortion, and (3) water-pouring may be performed to derive scaling values indicative of the transmit powers allocated to the eigenmodes. The first set of steering vectors, weights, and scaling values are used to derive a pulse-shaping matrix, which is used to precondition modulation symbols prior to transmission. At the receiver, channel eigen-decomposition is performed to derive a second set of steering vectors, which are used to derive a pulse-shaping matrix used to condition received symbols such that orthogonal symbol streams are recovered.
