| Abstract(in English) | This paper discusses OFDM (Orthogonal Frequency Division Multiplexing) with differential encoding assuming on acoustic communications. Acoustic waves increase the influence of maximum Doppler frequency and delay spread due to the slow propagation speed compared to radio waves. Therefore, acoustic communications has a serious issue in order to cope with time and frequency selective channels, i.e., double selective channels. It is well known that OFDM suppresses effect of ISI (inter-symbol interference) caused by delay spread. For the double selective channels, this paper compares FDDE (frequency domain differential encoding) which performs differential encoding in frequency domain with TDDE (time domain differential encoding) which performs differential encoding in time domain. Finally, computer simulation results confirm that delay spread degrades the performance of FDDE and TDDE has better performance compared with FDDE on double selective fading channels. |
