Efficient multimedia delivery over digital subscriber line

چکیده
We consider the design of a multimedia transmission systems to provide reliable and efficient delivery of multimedia data over digital subscriber line. The layers associated with different bit error performances are transmitted in parallel and the property of phone line channel is utilized to achieve unequal error protection efficiently. The transmitted power for the specified error performance is significantly reduced compared to the conventional schemes. Simulation results are provided for subband coded image and integrated services(video,voice and data), demonstrating excellent performance improvement, where a 0.5-2dB average power gain is achieved.

متن کاملATM over ADSL: The “Best-Effort” PVC Provisioning for ATM Call Flow
Asymmetric digital subscriber line (ADSL) is the latest copper-wire access technology that has the capability to deliver data rate up to 8 Mbps in downstream and up to 640 kbps in upstream. The ADSL Forum has also defined the model for ADSL/ATM connections. ADSL can be connected to ATM core network through the access network called digital subscriber line access multiplexer (DSLAM). This paper ...
متن کاملAdaptive DPD Modeling in DSL Customer Premises Equipment
Digital subscriber line (DSL) systems transport high-bandwidth data, such as multimedia, to service subscribers over ordinary twisted pair copper wire telephone lines. One of the important components of the DSL system is the line driver (LD) or the power amplifier (PA). The linearity of the LD is crucial to have a high-speed internet. Any non-linearity in the LD will create intermodulation dist...
