HWIL Channel Simulator for Communication System Testing

Welkin Sciences (WS) proposes to develop the Configurable Link Test Set II (CoLTS II), an affordable hardware-in-the-loop (HWIL) channel simulator design specifically for MDA test programs. Like the Defense Threat Reduction Agency's test sets, CoLTS II can distort real RF signals using the same disturbed propagation channel models found in COMLNK (a widely used software package for evaluating and testing modem designs hardened for HANE-disturbed channels). CoLTS II can also offset RF signals in delay and frequency to accurately emulate satellite and missile dynamics. The CoLTS II architecture will offer support for multiple channels (up to 40 in a single chassis) allowing for the testing of diversity receivers and Mulitiple In/Multiple Out(MIMO)communication system architectures.
