Abstract

We report on a student project implementing a D-QPSK modem on a TI C6711 DSK. The modem incorporates functionalities such as QPSK symbol generation, differential encoding and decoding, transmit- and receive filtering, quadrature modulation, timing synchronisation, and bit error detection. Both transmitter and receiver have to be operated concurrently and in real time. The DSK's on-board digital to analogue and analogue to digital converters were employed to interface the transmitted and received signals of the modem. Based on a set of specifications, the various solutions implemented by the students had to be compatible and be able to synchronise with each other.
