This paper is on the calculation of exact bit error rate (BER) of TCM M-ary APSK applicable to the DVB for multimedia data transmission. The current DVB-S2/S2x standards utilize the concatenated FEC coding (LDPC + BCH) for QPSK, 8PSK, M-APSK (M is 8 to 256). However this complicated coded modulations can be effectively combined into a single process using TCM. Although standards specify the average...
In this paper, a data-aided (DA) synchronization method is developed to jointly recover symbol-timing, frequency offset, and carrier phase for MF-TDMA on-board processing (OBP) satellite system. The estimates, which are obtained from a block of symbols transmitted through an Additive White Gaussian Noise (AWGN) channel and a fast Rayleigh fading channel, can be obtained with reduced computational...
Performance of two MCD (multi-carrier demultiplexer/demodulator) architectures (M-MCDD and PPF) for the on-board processing (OBP) satellite are analytically modeled and numerically evaluated in the presence of five critical degrading factors: narrowband AWGN, carrier frequency offset/phase offset, ISI and quantization error. Cumulative effects of these factors on two different MCD structures are also...
