Advanced Television Systems Committee (ATSC) 3.0 physical layer standard has adopts frequency interleaving scheme to mitigate burst errors caused by frequency selective fading in OFDM systems. In this paper, we briefly present the frequency interleaver of ATSC 3.0 and evaluate the performance on various wireless fading channel conditions.
DVB-T2 (The second generation Digital Video Broadcasting) is a system enhancement for the DVB-T system. The cyclic Q delay, cell interleaver and time interleaver are optional modules employed in the DVB-T2 system to increase the overall performance. The cell mapper module is used to build the T2 frames. The frequency interleaver module increases the ability of data recovery when facing channel noise...
This paper presents BER performances of OFDM/CDMA using combined frequency and time domain spreading (abbreviated as FT-CDMA). In the system, we employ a different frequency interleaver for each user and adaptive filters to suppress multiple access interference in an asynchronous multiple access system. In conventional MC-CDMA and MC-DS/CDMA systems, the improvement of BER performance can be obtained...
