A telecommunications platform has a cluster of processors which collectively perform a platform processing function. Plural processors of the cluster have Internet Protocol (IP) capabilities and respective plural IP interfaces. The plural processors of the cluster all have a same IP address. An Internet Protocol (IP) handler distributed throughout the cluster renders the IP interfaces of the plural processors of the cluster exchangeable so that knowledge of which one of the plural processors of the cluster is hosting an IP software application being accessed is unnecessary when selecting one of the plural IP interfaces for connecting to the cluster.

The system provides a gestural interface to various visually presented elements, presented on a display screen or screens. A gestural vocabulary includes 'instantaneous' commands, in which forming one or both hands into the appropriate 'pose' results in an immediate, one-time action; and 'spatial' commands, in which the operator either refers directly to elements on the screen by way of literal 'pointing' gestures or performs navigational maneuvers by way of relative or 'offset' gestures. The system contemplates the ability to identify the users hands in the form of a glove or gloves with certain indicia provided thereon, or any suitable means for providing recognizable indicia on a user's hands or body parts. A system of cameras can detect the position, orientation, and movement of the user's hands and translate that information into executable commands.

Each embodiment of the invention provides a signal coding and decoding method. The method comprises the following steps: receiving a flashing signal which comprises a binary code in the form of a gray scale image, wherein the binary code is a code based on the flashing time length and interval of flashing equipment; calculating the brightness value of an area in each frame of picture in the gray scale image of the received signal; and resolving corresponding information of the binary code based on the brightness value changes of the frames of the gray scale image. Through adoption of the method, message sharing can be performed without a mobile terminal or a short-distance communication way (such as Bluetooth and NFC (Near Field Communication)).

A transmitter 108 converts a digital baseband signal input 150 for transmission by an antenna 114 to support multiple communication standards. An over-deviation phase multiplier 130 increases signal phase deviation by a factor of M. A digital phase modulator 176 applies trigonometric lookup tables. A digital intermediate frequency up-converter 132 up-shifts frequencies of desired signal content. First and second digital-to-analog converters (DACs) 134 and 136 use relatively low-bit operations, which add DAC noise 212. First and second low pass filters 138 and 140 apply rejection above frequencies of desired signal content. An analog I/Q modulator 142 converts from complex to real signals, adding an unwanted signal spaced from the desired signal content by an intermediate frequency multiple. A limiter 144 reduces amplitude modulated noise. An over-deviation phase divider 146 divides signal phase deviation by 1/M to reduce phase modulated noise.
