Description: 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.

Description: TRec is a software to record telephone conversation by means microphone input of PC sound card.
It support voice level input detector and threshold level.
When running, the software always check the level of microphone input level.
If the level exceed the threshold, the software start to save recorded voice data to a file,
and also save the information to a table in database.

Description: This document will describe some of the general usage of MATLAB s Data Acquisition Toolbox (DAT). The software in the toolbox allows MATLAB to acquire
data from sensors and to send out electrical signals that can be used to control or
drive external devices. We will be using this toolbox with two different pieces of
hardware. One is the sound card built into your laptop, the microphone and speaker
will serve as the data acquisition (and output) devices. The sound card provides
convenience because it will allow you to test the DAT outside of the lab. We will
also be using Measurement Computing data acquisition cards that will ¯ t into your
laptops PCMCIA slot, these devices will be in the class laboratory. The data acquisition (DAQ) cards allow your computer to acquire data from many different types
of sensors.
