20130044025 | SATELLITE-BASED POSITIONING METHOD - A satellite-based positioning method is applicable in a Global Positioning System (GPS) receiver. The satellite-based positioning method includes the steps of obtaining multiple satellites in use by searching; calculating every satellite vector between each of the satellites in use and the GPS receiver; selecting three of the satellites in use in sequence as a satellite candidate set, searching for one of the satellite candidate set forming a geometric error relation according to the multiple satellite vectors, and using at least one of the satellites in use in the satellite candidate set forming the geometric error relation as a first satellite; searching for at least one second satellite in the satellites in use, wherein a signal strength varied rate of the second satellite is greater than a varied rate threshold; and using the satellites in use having the first satellite or the second satellite removed to perform positioning. | 02-21-2013 |
20130165057 | RF TRANSMISSION CIRCUIT AND ELECTRONIC DEVICE AND METHOD FOR SAVING POWER THEREOF - A radio frequency (RF) transmission circuit and an electronic device and a method for saving power thereof are provided. The RF transmission circuit includes: an antenna, at least one controller, a first path, a second path and a signal switching unit. The controller generates and/or receives RF signal. The controller has a determination function determining power of the RF signal and a switching function selecting or changing the transmission path of the RF signal as the first path and the second path. The first path transmits the RF signal to the antenna. The second path has a power amplifier to amplify the power of the RF signal and then transmit the amplified RF signal to the antenna. The signal switching unit selectively connects the antenna to the first path or the second path. When the first path is selected, the controller turns off the power amplifier. | 06-27-2013 |
20130285878 | ANTENNA SWITCHING CIRCUIT AND ELECTRONIC DEVICE AND ANTENNA SWITCHING METHOD THEREOF - An antenna switching circuit and an electronic device and an antenna switching method thereof are provided. The antenna switching circuit is disposed in the electronic device including an internal antenna and a RF module, and includes an external antenna connector and a controller. The external antenna connector has an independent ground terminal for receiving an independent ground signal, and the external antenna connector is electrically connected to an external antenna. The controller has a first RF terminal, a second RF terminal and a control terminal, the first RF terminal is electrically connected to the RF module, the second RF terminal is electrically connected to the internal antenna, and the control terminal detects the independent ground signal. When the controller detects no change in the independent ground signal, the controller electrically connects the RF module to the internal antenna; otherwise, the controller electrically connects the RF module to the external antenna. | 10-31-2013 |
