Duobinary signaling and decoding pdf


March 07, Committee Members: In order to solve this duobinary signaling and decoding pdf, a simple new architecture of a duobinary system to be used with the commercial, off-the-shelf FPGAs is proposed. Umar, Ashraf Ibrahim Graduate Program: The standard duobinary duobinary signaling and decoding pdf architecture is modified by placing the duobinary encoder after the transmit equalization, before the channel, while the duobinary decoder is placed immediately after the channel, before receiver equalization is performed.

Most of the past research in duobinary and PAM-4 was concentrated on simulations of the performance of coding and equalization techniques to compensate for the channel distortion. A typical duobinary transceiver system comprises of an encoder at the transmitter and the corresponding decoder at the receiver. In order to address this issue two common techniques exist: Master Thesis Date of Defense:

A correlation between the simulated and measured NRZ data is made and the results show a high degree of correlation.

Umar, Ashraf Ibrahim Graduate Program: In order to solve this problem, a simple new architecture of a duobinary system to be used with the commercial, off-the-shelf FPGAs is proposed. Two real-world channels were used:

High speed communication channels, including backplanes, always have distorting effects on signals being transmitted through them. Two real-world channels were duobinary signaling and decoding pdf Eye diagram scopes in Simulink are used to view the simulation results. This scheme offers the advantage of allowing us to use the FPGA equalizers in the NRZ coding without having to modify them to support the three-level duobinary signal. Simulink was used for the NRZ simulation and Quartus for hardware implementation.

In order to address this issue two common techniques exist: March 07, Committee Members: Duobinary signaling and decoding pdf duobinary signal generated is a three level signal which current commercial FPGAs are not capable of handling. Simulation of this architecture is performed in Simulink, and results obtained show that hardware implementation of such architecture is feasible as the transmitted data is reliably recovered at the receiver. NRZ and duobinary coding are chosen because they are generally less complex than PAM-4, which makes them a good choice for higher data rates.

The duobinary signal is then transmitted to the communication channel. March 07, Committee Members: High speed communication channels, including backplanes, always have distorting effects on signals being transmitted through them.

Two real-world channels were used: At the receiver side, the duobinary decoder is implemented using a signal splitter, two comparators, and an XNOR gate. The BER for NRZ and duobinary were also computed for both channels the results were comparable; however, the duobinary uses half of the bandwidth.

A typical duobinary transceiver system comprises of an encoder at the transmitter and the corresponding decoder at the receiver. Duobinary signaling and decoding pdf correlation between the simulated and measured NRZ data is made and the results show a high degree of correlation. Hence, this modified architecture takes advantage of the well-developed digital signal processing blocks in commercial FPGAs while allowing faster development times.
