Software Radio Demodulator
for demodulating diverse signals
A member of Filtronic Sigtek’s high performance VME software radio family, the
ST-135 high performance software radio demodulates a growing set of signals
including BPSK, DBPSK, QPSK, DQPSK, FSK and MSK. Bit rates from 1.2 Kbps
to 32 Mbps with future growth to 40 Mbps and beyond. The expandable software
radio architecture allows addition and enhancement of demodulation types.
Control software includes a JavaTM control application for TCP/IP remote
operation and NT device drivers. Options include a direct sequence CDMA
spread spectrum receiver and FEC decoder.
