A binary ASK transmitter and receiver is designed to transmit digital information over a "speaker-air-microphone" (SAM) channel. Listening to the channel while making parameter adjustments and viewing plots builds additional insights into the ASK modulation scheme. This project describes the various tradeoffs affecting bandwidth and information rate and provides an application for the pulse shapping transmit filter. (less)

PAM Transmitter and Receiver Implementing Coherent Detection

The integrate-and-dump detector is fundamental to coherent detection, the optimal receiver technique that minimizes bit error rate (BER) for a given signal-to-noise ratio Eb/No. In this project develop a pulse amplitude (PAM) transmitter based on a transmit filter to map a bitstream onto a signaling waveform (rectangular and Manchester pulse shapes), an additive white Gaussian noise (AWGN) channel, and a receiver that implements integrate-and-dump detection. All waveforms throughout the signal processing chain are presented as a stacked chart indicator with a speed control to permit generated waveforms to be studied slowly (i.e., the integrator output ramping up or down) or quickly to process long message bitstreams. Visualizing the critical system signals as waveforms facilitates exploration of the effects of specific values of BER and Eb/No, and promotes deeper understanding of coherent detection. (less)
