摘要： A method (10 or 500) and system (200) for simulating and improving accuracy of empirical propagation models for radio frequency coverage can include a display (210) and a processor (202) coupled to the display. The processor can be operable to input (502 and 504) low-resolution data and high-resolution data, select (506) an area of interest being simulated for empirical propagation models, and classify (508) receivers as belonging to a predetermined type of object. If a receiver in the area of interest is a low resolution object, then normal losses can be applied (510). If a receiver in the area of interest is a high resolution object, then losses specific to the high resolution object can be applied (512). If a receiver is classified as being inside a building, then the processor can further compute (516) a median power for a location of the receiver and add in-building penetration losses.

摘要： An antenna system (205) includes an antenna structure (215), a receiver (220), and an antenna system controller (225). The antenna structure includes an arrangement of antennas (237), a signal combiner (240), and a switching matrix (235). The arrangement of antennas is designed to have a set of antenna element separations that are optimized to provide lowest correlation coefficients of intercepted radio signals for a corresponding set of electromagnetic environment types that vary from a very low density scattering environment to a maximum density scattering environment. The antennas (230), (231), (232), (233), (234) in the antenna arrangement each include at least one element that has a common polarization. There is at least one antenna that is a dual polarized antenna. The antenna system selects an antenna element pair that corresponds to the environment type which it is operating and thereby receives a best combined signal.

摘要： Communication systems include a transmitter that modulates a radio signal transmitted from two differently polarized antennas during a state time in which a wave state of the radio signal conveys information and is based on one or more polarization states selected from a constellation of polarization states comprising at least three polarization states. The communication system includes a receiver that intercepts the radio signal by two differently polarized antennas during the state time, and demodulates the signal. The polarization states may identify user devices or may quantify a portion of the information intended for a user device.

摘要： A method (600) and simulation tool (200) having enhanced accuracy and speed for simulation using ray launching in a mixed environment (20) by using adaptive ray expansion mechanisms can include a memory (204) coupled to a processor (202). The processor can select (602) a target area within the mixed environment and modify (604) the propagation properties of the adaptive ray expansion mechanisms according to characteristics classified for the target area. The processor can further classify characteristics for the target area by transmitting and reflecting rays for indoor building regions and for outdoor building regions. The number of bounces or a power level threshold assigned to a transmitted ray is a function of the environment where it propagates. The simulation tool can determine the target area or a region of interest by using a global positioning service device (230) externally attached to a device performing functions of the simulation tool.
