چکیده
© 2010 ETRI Journal, Volume 32, Number 2, April 2010 We propose a new matched filter architecture for chirp spread spectrum in IEEE 802.15.4a. By using relations among the four subchirps, the proposed architecture comprises four subfilters utilizing only a set of coefficients matched to the first subchirp. The four subfilters share adders and registers, and as a result, the required adders and registers for implementation are reduced.

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 کاملOn the architecture and performance of an FFT-based spread-spectrum downlink RAKE receiver
This paper describes a spread-spectrum downlink RAKE receiver that computes a data detection in the frequency domain. We assume a pilot signal is transmitted with data signals for channel sounding. The pilot signal does not degrade the receiver bit error rate (BER) performance because the receiver estimates the pilot signal and subtracts the estimated pilot signal from the received signal befor...
متن کاملA Low-Rate Wireless Spread-Spectrum Communication Technique using Linear Step FM Signal
A low data-rate communication technique using linear step frequency modulated (LSFM) signal is presented. When the carrier frequency offset (CFO) between the transmitter and the receiver is significant comparing to the symbol rate, the techniques using normal signaling waveforms with matched filtering become infeasible. In this scenario, wideband chirp (linear FM) signal is feasible because of ...
متن کاملA New Receiver Structure for Performance Enhancement in CSS
We propose a new receiver structure for chirp spread spectrum (CSS) based on the characteristics of the CSS signals which are alternatively transmitted in low and high band in order to improve detection performance. The conventional channel filter performs the filtering of entire signal bandwidth in a passband, but there happens a problem that excessive noise in neighboring sub-band is added wh...

This letter proposes a high precision ranging scheme based on the time of arrival estimation technique for the IEEE 802.15.4a chirp spread spectrum system. The proposed scheme consists of a linear channel impulse response estimation process with the zero forcing or minimum mean square error technique and the multipath delay estimation process with matrix pencil algorithm.
