Random code length polar encoding method

A random code length polar encoding method includes: during construction of a polar code, if the code length is not the power of 2, using a group of virtual channels with the capacity of zero for supplementing the channel number to be the power of 2; performing mixed mapping for each channel according to the capacity equalization principle; and performing polar conversion for the obtained channels, selecting the channels with higher capacity from converted channels according to the designed bitrate for transmitting information bit sequences, and using the rest channels for transmitting a known fixed bit sequence of a receiving end and a transmitting end. The method enables polar encoding to allow the code length to be an optional positive integer and is applicable to multi-carrier and high-order modulation systems, and the added perforating operation enables the encoding bit sequences outputted by an encoder to be optional in length; by means of channel mixed mapping, polar encoding can adapt to different component channels of parallel channels, so that anti-noise performance is good; and flexibility of using polar codes for a practical digital communication system is greatly improved, and accordingly the method has good application prospect.

Incremental redundancy transmission for multiple parallel channels in a MIMO communication system

For incremental redundancy transmission on multiple parallel channels in a MIMO system, a transmitter processes (e.g., encodes, partitions, interleaves, and modulates) each data packet for each parallel channel based on a rate selected for the parallel channel and obtains multiple symbol blocks for the packet. For each data packet, the transmitter transmits one symbol block at a time on its parallel channel until a receiver recovers the packet or all blocks have been transmitted. The receiver performs detection and obtains symbol blocks transmitted on the parallel channels. The receiver recovers the data packets transmitted on the parallel channels independently or in a designated order. The receiver processes (e.g., demodulates, deinterleaves, re-assembles, and decodes) all symbol blocks obtained for each data packet and provides a decoded packet. The receiver may estimate and cancel interference due to recovered data packets so that data packets recovered later can achieve higher SINRs.

Optical device utilizing optical waveguides and mechanical light-switches

An optical device consists of one or more optical waveguides and mechanical light switches 30. When a light switch 30 is turned on, it extracts light beam 62a from a waveguide core 20 and redirect the light beam 62b into free space, it redirects an incoming light beam 80 from free space and injects the light beam 80a into the waveguide core 20, or it performs both functions at the same time, depending on specific applications. On and off states of a light switch 30 are achieved by pulling the light switch 30 into a close vicinity of the waveguide core 20 and by pushing the light switch 30 away from the waveguide core 20, respectively. An interactive fiat-panel display can be built based on this invention. A plurality of parallel channel waveguides forms a display panel. An array of light beams 62a, injected from an array light source 60, propagates along waveguide cores 20 until reaches a location where a light switch 30 is turned on. At this location, the light switch 30 redirects the light beams towards a viewer. An image is produced when the light switches 30 are turned on sequentially while the light-intensity distribution on the array light source 60 is synchronically updated. The panel display is capable of responding to an input optical signal by detecting an incoming light beam 80 from a light pen 100. An array of photodetectors 81 is used to identify the location of the incoming light beam 80 on the display panel and a computer is used to execute a corresponding action accordingly.

Examples of local communication systems are disclosed, based on a ring of point-to-point links, providing for transport of fixed rate synchronous, fixed rate asynchronous data and variable rate data in a flexible format. Different segments of the ring network can carry data at different bit rates, while remaining synchronized to a common frame rate and having a common control channel structure, for compatibility with earlier systems. Parallel channels are provided, either permanently or when required, for signalling errors of source data, data validity / padding, flow control. Parallel variable width channels are defined with free content (stream or packet). Null data symbols are defined for padding on a byte-by-byte basis. The allocation of capacity among variable width channels is revised block by block, and a transition period is defined to allow for ring latency. Calculations for allocation of capacity are performed during one block for the next block, locally at each source station, according to predetermined rules. Information as to bandwidth requirements is exchanged prior to the calculation via a special connection signalling channel and message format.

Modular disk memory apparatus with high transfer rate

A modular disk memory apparatus provides a modularly expandable, multi-gigabyte auxiliary memory for a computer or other host electronic device, and includes multiple, parallel serial data channels to maximize bidirectional data transfer rates between the apparatus and the host device. Maximization of READ / WRITE data transfer rates within the apparatus is achieved by utilizing a large number of small hard disk drives, typically eight 2.5-inch drives on each of a plurality of Disk Storage Modules, each including a plug-in printed circuit board capable of holding two 5-+E,fra 1 / 4+EE inch drives, thereby increasing the maximum data transfer rate per unit volume of the modules by a factor of two. Maximization of bidirectional data transfer rates between the apparatus and host device over that attainable using a single serial data channel such as a coaxial, quadaxial or fiber optic cable, is achieved by parsing or demultiplexing data to be transmitted from a single parallel channel onto p paralleled cables, thereby increasing the maximum transmittal rate by p. Data received over the parallel data channels is multiplexed or concatenated to comprise a data stream on a single parallel channel. Reconstruction data is embedded in data contained in the p parallel data channels specifying the number q of channels employed, where 1< / =q< / =p thereby configuring the demultiplexer to concatenate that number of data channels onto a single parallel data bus.

Adaptive dynamic range receiver for MRI

A receiver for a resonance signal of a magnetic resonance imaging system generates a baseband signal for image processing by dividing a raw resonance signal among multiple parallel channels, each amplified at a respective gain. A digital channel selector determines, at any given moment, a lowest-distortion channel to be further processed. Amplitude and phase error compensation are handled digitally using complex multipliers, which are derived by a calibration, based on a simple Larmor oscillator, which can be done without the need for a sample and without repeating when measurement conditions are changed. One of the important benefits of the invention is that it provides for gain selection without repeated calibration steps. This is particularly important in systems that employ fast imaging techniques such as fast spin echo, where the invention can speed imaging substantially.

Once the probe has been selected, it receives an address from the system server, stores the address in its memory, acknowledges this to the system controller, and sends a signal on the select channel to the next probe. Accordingly, initialization of a battery monitoring system is easily performed. The invention also lies in an interface device for use with a battery monitoring system.
