This project aim was to build wireless software modem for data communicaTIon between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz – 16,000Hz). The test files used as information files were text files. This goal was attained both in an incoherent scheme and in a coherent scheme. Build under Matlab code, our modem uses OFDM (orthogonal frequency division multiplexing) modulation, synchronization by LMS sequence, channel estimation (no equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of 2 or 4. To optimize the probability of error, these symbols were mapped using Gray mapping. Report

To fully utilize the available spectrum for a wireless communicaTIon system it is feasible to adapt to different situations on the channel. In this paper a flexible OFDM transmitter is presented together with basic theory behind OFDM transmission. It is shown that high flexibility can be obtained with a reasonable amount Flexible baseband transmitter for OFDM of additional hardware. Part of the design, the FFT-processor, has already been fabricated and measurement results are presented.
