In this paper, performance of a wireless communication system based on wideband signals has been experimentally evaluated in a point-to-point topology for potential deployment in industrial environments. A class of wideband signals based on Chirp Spread Spectrum (CSS) modulation has been chosen in this work. Two experimental scenarios have been considered: 1) coexistence with other wireless systems,...
Channel estimation is a significant component of any receiver implementation. This paper presents a fast non-iterative channel estimation and equalization algorithm for TDS-OFDM systems. The proposed method is a hybrid of CP-OFDM and ZP-OFDM systems. By discarding the initial portion of the PN-sequence that absorbs all the ISI, the channel can be estimated from the remaining PN-sequence by using the...
