Variable-rate adaptive trellis coded QAM for flat-fading channels
A bandwidth-efficient variable-rate adaptive channel coding scheme, ATCQAM, for time-varying flat-fading channels is proposed. In addition to the forward channel, a low-capacity feedback channel is needed to convey channel state information to the transmitter, possibly with delays and noise. A number of transmission modes, with varying throughputs, are incorporated at the transmitter. Appropria...
متن کاملA Frequency Domain Variable Data Rate Frequency Hopping Channel Model for the Mobile Radio Channel
Modeling of the mobile radio channel is considered. Starting from a physical model, a frequency domain description of the channel is obtained. It is then shown that the effect of fading and dispersion can be entirely modeled using frequency transform techniques. Due to the bandlimitation of the simulated stochastic processes, the channel impulse response (CIR) model works on discrete time sampl...
متن کاملA Full-Fuzzy Rate Controller for Variable Bit Rate Video
In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...
متن کاملA Comparison of Selected Gbn Arq Schemes for Variable-error-rate Channel Using Qam
In non-stationary channels, error rates vary considerably. The paper compares Yao’s Adaptive Go-backN (GBN) Automatic-Repeat-Request (ARQ) scheme with Adaptive go-back-N with sliding window mechanism which both estimate the channel state in a simple manner, and adaptively switch their operation mode. The throughput of these schemes is compared in conditions of Additive White Gauss Noise (AWGN) ...

Finally, in section 4, we A high bandwidth efficiency variable rate adaptive channel conclude with a summary of results. coding scheme, ATCQAM, is proposed. Known pilot symbols are transmitted periodically to aid demodulation. Past channel states are fed back to the transmitter with delay. Current 2 Ada...
