摘要： A device for site monitoring is disclosed. The device may include a communication interface configured to receive site monitoring data from a site monitoring system. The communication interface may also be configured to wirelessly transmit the site monitoring data to a base station. The site monitoring data may include a device identification. The device also may include a processor and memory. The memory also may include two pseudonoise (PN) codes, namely a first PN code and a second PN code. The site monitoring data may be received from the site monitoring system. The site monitoring data may be spread using the first PN code to provide first spread site monitoring data. The first spread site monitoring data may be spread using the second PN code to provide second spread site monitoring data. The second spread site monitoring data may be transmitted using a burst direct sequence spread spectrum radio signal.

摘要： A radio frequency (RF) receiver system that is configured to achieve high dynamic range may include at least one antenna and a plurality of receivers connected to the at least one antenna. The plurality of antennas may be configured to provide different gains. The RF receiver system may include an analog-to-digital (A/D) converter subsystem connected to the plurality of receivers. The A/D converter subsystem may include a plurality of A/D converters. An overall digitization range of the A/D converter subsystem may be greater than a digitization range of any of the plurality of A/D converters individually. The overall digitization range of the A/D converter subsystem may be sufficiently large so as to accommodate a desired dynamic range of the RF receiver system.
