Chirp Spread Spectrum Transceiver Design and Implementation for Real Time Locating System
A chirp spread spectrum (CSS) transceiver architecture for IEEE 802.15.4a is proposed and implemented. In the transmitter, the size of the read-only memory that stores CSS signal samples for the chirp modulator is reduced by removing duplicate samples among subchirps. In the receiver, a matched filter is utilized to remove the other band noise caused by the band hopping property of CSS. A robus...

متن کاملAn Interpolated Frequency-Hopping Spread-Spectrum Transceiver
A technique of spread-spectrum transmission, interpolated frequency-hopping (IFH), is presented. IFH employs a carrier that moves smoothly and continuously in frequency, helping to alleviate problems, such as spectral splatter and transient mismatch, which are a concern in conventional phase-locked loop (PLL)-based frequency-hopping spread-spectrum systems. In IFH, the pseudorandom hopping code...
متن کاملThe Design and Implementation of a Semi-Custom Transmitter for a CDMA Direct Sequence Spread-Spectrum Transceiver
High-performance wireless communications systems allow access to real-time data located on a high-speed network using portable, lowpower terminals. For a pico-cellular network, a basestation within each cell serves as the interface between the backbone network and the various mobile units. A CDMA direct sequence spread-spectrum transmitter is presented which allows the basestation to provide a ...
