Spatial-temporal compression of sensing data from a plurality of sensors involves using a plurality of sensors to obtain measured physical data associated with a plurality of sensed elements. At each of a plurality of sampling times a set of N sampled data is acquired from the N sensed elements corresponding to the measured physical data. The sets of sampled data are analyzed to obtain statistical characteristic information. Thereafter, one or more frames of compressed data is generated using the statistical characteristic information to facilitate temporal and spatial data compression.

Spatial-temporal compression of sensing data for sensor network

Method for data communication involves receiving with a radio receiver a data signal containing a plurality of data symbols. An analog to digital converter obtain a sample of the data signal at periodic intervals to define a sampling rate which is N times a symbol rate. Thereafter, at least one processing device allocates each sample obtained to a respective one of N sampled data streams in accordance with an allocation sequence, and repeats the allocation sequence after every N samples so that each of the N sampled data streams has a data stream symbol rate equal to the symbol rate. Thereafter, a plurality of data stream data sets defined by the N sampled data streams are validated. Once the validation is completed, a plurality of groups are determined, each comprised of two or more of the stream data sets which have been validated and are identical.

Fast data acquisition in digital communication

A Wireless battery area network permits the wirelessly monitoring and controlling of individual batteries within large-scale battery applications. The system automatically configures its wireless nodes in the network and provides for the linking of a plurality of batteries () to a master battery management unit (M-BMU) () by establishing a wireless battery area network within a battery pack that include slave units (S-BMU) (). The entire system may also be controlled by a top level battery management unit (T-BMU) (). The system and method allows for the monitoring of voltage, current, temperature, or impedance of individual batteries and for the balancing or bypassing of a battery.
