Burst-by-Burst Adaptive Wireless Video Telephony over Dispersive Channels

Burst-by-Burst Adaptive Wireless Video Telephony over Dispersive Channels
Burst-by-Burst Adaptive Wireless Video Telephony over Dispersive Channels
The video performance benefits of burst-by-burst adaptive modulation are studied, employing a higher order modulation mode, when the channel is favourable, in order to increase the system's bits per symbol throughput and conversely, invoking a more robust, lower order modulation mode, when the channel exhibits inferior channel quality. It is shown that due to the proposed adaptive modem mode switching regime a seemless video-quality versus channel quality relationship can be established, resulting in error-free video quality right across the operating channel Signal-to-Noise Ratio (SNR) range.

Abstract

The video performance benefits of burst-by-burst adaptive modulation are studied, employing a higher order modulation mode, when the channel is favourable, in order to increase the system's bits per symbol throughput and conversely, invoking a more robust, lower order modulation mode, when the channel exhibits inferior channel quality. It is shown that due to the proposed adaptive modem mode switching regime a seemless video-quality versus channel quality relationship can be established, resulting in error-free video quality right across the operating channel Signal-to-Noise Ratio (SNR) range.
