Acquisition of pseudonoise sequences in direct-sequence spread-spectrum systems
… schemes for the acquisition of a pseudonoise (PN) sequence in a baseband direct sequence spread-spectrum (DS/SS) system are investigated. First, we consider acquisition schemes for receivers with chip synchronization, that is, the chips of the transmitter and receiver PN sequence generator are …

Serial acquisition of PN sequences in direct sequence spread spectrum communication systems
… schemes for the acquisition of a pseudo-noise (PN) sequence in a direct-sequence spread-spectrum (DS/SS) communication system. Serial search acquisition schemes are by far the most commonly used class of acquisition schemes, due to the ease with which they are implemented. The main assumptions …

Design, Analysis And Implementation Of Orthogonal Frequency Coding In Saw Devices Used For Spread Spectrum Tags And Sensors
… coding can be added using a pseudo-noise (PN) sequence. The OFC approach is general and should be applicable to many differing SAW sensors for temperature, pressure, liquid, gases, etc. Device embodiments are shown and a potential transceiver is described. Measured device results are …

Energy-Efficient Multicarrier and Multicarrier-CDMA Systems
… based on symbol statistics; ii) Partial Transmit Sequence (PTS) using Magic square pattern and adjacent partitioning; and iii) Selective Mapping (SLM) and Tone Reservation (TR) with reduced complexity. These methods are described and algorithms are presented for computation of Peak-to-Average …

Low-Power System Design for Impedance-Based Structural Health Monitoring
… method, which uses a pseudorandom noise (PN) sequence for excitation of the structure rather than a signal with a particular waveform. The wideband method simplifies generation of the excitation signal and eliminates a digital-to-analog converter (DAC). The system form factor and power …

Lokalizace akustických zdrojů metodou TDOA
Práce se zabývá teoretickým a praktickým řešením akustické lokalizace metodou TDOA. Rozvádí návrh schémat pro vysílač a přijímač. Dále uvádí způsob komunikace mezi procesorem, který vyhodnocuje přijatý signál, a počítačem, jež výsledek zobrazuje ve srozumitelné podobě. A nakonec se zabývá návrhem …
