摘要： A wireless communication system experience interference from other wireless communication networks. A method for designing wireless communication systems subject to interference is proposed based on a realistic interference model which accounts for the propagation effects introduced by the wireless environment (such as path loss, shadowing, and multipath fading), and for the spatial scattering of transmitters (using a Poisson field). The method accounts for tradeoffs between network parameters, such as signal-to-noise ratio (SNR), interference-to-noise ratio (INR), path loss exponent, spatial density of the interferers, and error probability. Advantages of this method include: 1) a unified framework for designing a wireless system, subject to cumulative interference and noise, incorporating a wide range of performance metrics; and 2) a general application that covers a broad class of wireless communication systems and channel fading distributions.

摘要： In a cooling apparatus, air within a room is first introduced into a radiator-type adsorber (1), where moisture contained in the air is adsorbed by A-type silica gel. The resulting low-humidity air is subsequently introduced into a desorption cooler (5), where moisture is desorbed from B-type silica gel, thereby humidifying and cooling the air. The resulting low-temperature air is then used for cooling. When a cooling capacity of the cooling apparatus is lowered, air from a heat source is introduced into the radiator-type adsorber (1), where the moisture is desorbed from the A-type silica gel, thereby recovering the adsorbability thereof. The high-humidity air resulting from the desorption of the moisture is subsequently introduced into the desorption cooler (5), where the moisture contained in the air is adsorbed by the B-type silica gel, thereby recovering the desorption cooling capacity thereof.

摘要： An apparatus is provided for cutting a resin-coated metal pipe. The apparatus includes first and second spaced apart pairs of holding members for holding the pipe. First and second cut-off blades are movable between the pairs of holding members for making substantially diametrically opposed pre-cuts in the pipe. The cutting members move substantially in the same tangential direction to substantially balance rotational forces on the pipe. A cut blade then is penetrated through the pipe from the one pre-cut to the other to provide a clean precise cut in the pipe.

摘要： A method and a system discover a wireless LAN network for a multi-mode handset in a power-efficient way. The method extends stand-by time for the cellular and wireless LAN multi-mode handset, taking advantage of that fact that the cellular interface demands less energy from the battery than the wireless LAN (WLAN)-based interface in such a handset. The method therefore uses the cellular interface as an always-on proxy for the wireless LAN interface to receive the initial packets of a communication session, and uses the initial packet or packets to activate the handset's interface with the wireless LAN.

摘要： Systems and methods are provided for a distributed inter-cell interference avoidance (ICIA) technique for avoiding co-channel interference between femtocell networks and macrocell networks. At the macrocell, user equipments sense the downlink (DL) spectrum and detects whether there are any nearby interfering femtocells. If there is any interference, a macrocell base station appropriately re-schedules the DL resources and also uses a mapping function to re-schedule uplink (UL) resources based on the re-scheduled DL resources. At the femtocell, a femtocell base station senses the UL spectrum to detect for interference from nearby macrocell users. If there is interference, femtocell gives priority for use of the resources to the macrocell by releasing UL resources. Femtocell may also use the same mapping function to obtain the DL resources used by the macrocell and to re-schedule DL and UL resources of the femtocell to avoid using the DL and UL resources of the macrocell.

摘要： In a geolocation application, a method is provided to jointly estimate the time-of-arrival (TOA) and the amplitude of a received signal based on super-resolution technique. The super-resolution joint TOA-amplitude estimators are provided based on either the expectation-maximization (EM), parallel-interference-cancellation space-alternating generalized expectation maximization (PIC-SAGE) or serial-interference-cancellation SAGE (SIC-SAGE). The SIC-SAGE estimator minimizes the ranging estimation error especially under a non-line-of-sight (NLOS) condition. The SIC-SAGE estimator is a simplified version of the maximum likelihood estimator with more stable performance in a multipath rich environment, such as the ultra-wideband (UWB) based applications. These techniques provide the following benefits: 1) it is generic, so that signal processing can be deployed on both time-domain (e.g., UWB impulse-radio) and frequency-domain (e.g., multi-band orthogonal frequency-division multiplexing (MB-OFDM)) based transceiver schemes and applicable for both UWB and non-UWB systems; 2) it is robust especially under NLOS condition and multipath rich environment.
