System Design, Development, Training and Implementation of a Mixed Signal Broadband Chip-to-Chip Digital Communication System


At Prairie View A & M University, we developed a new Mixed Signal Systems and Broadband Access Technology Laboratories over the last few years. These laboratories are used in helping our premier Semiconductor and Telecommunication companies in their various areas of research needs, such as, mixed signal design, testing and in interoperability and reliability studies. These laboratories are used also for the training of our students in these emerging areas of technology and for research, especially, the Digital Subscriber Line (DSL) broadband mixed signal technology.

As the paper will demonstrate, we introduce our students to the modeling and simulation of an 8- Pulse Amplitude Modulation (PAM) transceiver that can be fabricated using the Complimentary Metal Oxide Semiconductor (CMOS) transceiver technology. The transmitter incorporates a pattern generator and a pseudorandom bit sequence (PRBS) generator, which are multiplexed to a 3-bit digital-to-analog converter (DAC) with pre-emphasis. The receiver integrates three 3-bit analog-to-digital converters (ADCs) for over sampling of the transmitted data. The modeling and simulation design was implemented using Matlab/ Simulink platform.

This modeling and simulation design is developed and implemented using an 8-PAM system, which partitions the data from the transmitter into 3-bit, 8-level quantized form. This type of multi-signaling reduces the symbol rate and thus limits data error in the receiver. To boost the efficiency and reliability of the system, three ADCs are used, instead of one, sampling three times the channel data rate. In this design, a special data select code is written with Matlab/Simulink platform to recover the transmitted data. The data from the transmitter is recovered by error correction technique using the Matlab code.

As part of our goal in the Electrical Engineering and Engineering Technology Departments to expose our students to hands-on training, the students are given the opportunity to model, simulate and implement the software system design in the broadband (high-speed) communication and mixed signal systems laboratories. The results of these implementations have been encouraging. The lessons learned, future work and recommendations are discussed in this paper.
