According to the system requirements, the multicarrier OFDM transmission scheme was proposed in intra-flight data link (IFDL) physical layer. Considering the anti-jamming vulnerability, the reliabilities of OFDM system were quantitatively analyzed under several burst interference. Combined with the convolution interleaving, (255,223)RS-(2,1,7) convolution concatenated coding that was proposed originally...
The bit error rate (BER) performance analysis of an OFDM wireless communication system is carried out considering the effect of fading and multipath dispersion. Further, forward error correction coding such as convolutional coding (CC) is also applied to improve the BER of OFDM-wireless communication system. Significant improvement in receiver performance is obtained by numerical computation.
Orthogonal frequency division multiplexing (OFDM) is the modulation scheme of choice for digital video broadcasting-handheld (DVB-H), which is required to operate under high mobility conditions resulting in significant Inter-carrier Interference (ICI). To mitigate ICI, several cancellation schemes have been proposed but they require reliable channel information at the receiver which is quite challenging...
Correlative minimum shift keying (MSK), a second order polynomial modulation scheme known as tamed frequency modulation (TFM), is a constant envelope type of modulation with a perfect peak to average power ratio (PAPR), besides the property of low out of band power. We apply the linearized TFM to the single carrier transmission with frequency domain equalization (SC/FDE) concept. We then obtain a...
