Reliable video transmission over mobile wireless channels faces many challenges due to the time-varying multi-path fading. In this paper, a novel 3-D interleaving method, called Spatial Frequency Temporal Interleaving (SFTI), is proposed for video transmission over OFDM systems in this kind of channels. SFTI means the video data will be interleaved both at bit level in spatial domain, which can disperse...
We propose a new SNR estimation method based on the preamble for OFDM systems in frequency selective channels. The OFDM training symbols in the preamble are equalized by the known data in frequency domain and employed to estimate the noise variance. The second order moments of the received symbols are used to estimate the signal plus noise power in the OFDM packets. The SNRs on the subchannels and...
