SMSTransceiver (short message service transmItter and receiver [transceiver]) is a tool for sending and receiving SMS via a serial or infrared connection between PC and a mobile phone.
This paper presents the key circuits of a 1MHz bandwidth, 750kb/s GMSK transmItter. The fractional-N synthesizer forming the basis of the transmItter uses a combined phasefrequency
detector (PFD) and digital-to-analog converter (DAC) circuit element to obtain >28dB high frequency noise reduction when compared to classicalfrequency synthesis.
M-file uses random data which BPSK modulates a carrier to configure a BPSK UWB transmItter. The receiver demodulates the BPSK UWB carrier and the data is recovered
