Abstract: A system for testing advanced antennas includes an antenna unit controller, a radio frequency instrument, and a test controller. The antenna unit controller is configured to connect to a device that includes an advanced antenna under test in an anechoic chamber. The radio frequency instrument is connected to a probe antenna in the anechoic chamber. The test controller is configured to control the test of the advanced antenna by controlling the antenna unit controller to reconfigure the advanced antenna under test, and by controlling the radio frequency instrument to communicate wirelessly with the device via the probe antenna in each of a sequence of multiple configurations of the advanced antenna while the advanced antenna remains in the anechoic chamber.

Abstract: An encoder uses orthogonal dispersion sequences to encode symbols of an applied symbol stream as a series of microbursts that are separated by variable time intervals established by the time dispersion sequences. A decoder selects one or more series of microbursts from a composite set of microbursts received by the decoder, based on dispersion sequences at the decoder that match the dispersion sequences used to encode the one or more series of microbursts. Each selected series of microbursts is then conditioned to extract a corresponding symbol stream.

Abstract: A data decoding scheme operates on individual code symbols within an encoded data stream, enabling data to be recovered from the code symbols at a high rate. The decoding scheme, typically included within a receiver of a digital communication system or data network, does not rely on processing and storing multiple code symbols and is unencumbered by storage memory elements and decoding rate limitations associated with receiving and processing blocks of multiple code symbols. The decoding scheme generates bit sequences corresponding to each alternate data state of a received code symbol. Error vectors are generated as a result of comparing each of the generated bit sequences to the received code symbol. The data state of data represented by the code symbol within the encoded data stream is recovered from the code symbol by selecting the minimum of the generated error vectors.
