| Popis: | This paper addresses the concatenation of a convolutional code and COFDM/OQAM modulation transmitted over a time-dispersive radio channel. The proposed receiver is composed of a suitable OFDM/OQAM filter-bank demodulator, followed by an intersymbol and inter(-subchannel) interferences canceller and a SISO (Soft Input - Soft Output) decoder put in Turbo-like mode. The iterative algorithms are based on message passing on bipartite graphs. As an example, performance comparison with the linear subchannel equalization is presented. |
