In certain aspects, the invention provides systems and devices that include a digital/analog converter configured to operate with a computer processor and memory to send or receive an analog signal over a communication line that includes a plurality of signals having known frequencies. Inbound receiving sub-systems or devices sample the analog signal and measure a quality of the sampled, digital signal to evaluate the communication line. The key differentiator is the recognition that the human mouth and ear are intrinsically analog without encryption. By locating the test device as close to the user as possible, this system incorporates testing of complex communication streams including numerous variables and transforms (e.g. encryption, Analog to digital, Voice over IP, packet switching, ATM, SONET). Ultimately, it provides a simple interface to convert qualitative analysis to quantitative (numerical) analysis.

Abstract: A node in a first network requests a communication channel from a second network. Upon receiving a channel assignment, nodes in the first network employ the assigned channel for communicating in a manner that is transparent to the second network. A transmitting node selects a decoy data signal as a carrier signal, synthesizes data-bearing channel distortions; and distorts the carrier signal with the channel distortions prior to transmission. An undistorted version of the decoy data may be transmitted to an intended receiver. The receiver distinguishes between the synthesized data-bearing channel distortions and natural channel distortions to decrypt the data. In a MIMO system, the transmitter generates a MIMO precoding matrix from a message to be sent to the receiver and multiplies the decoy data signal vector with the MIMO precoding matrix.
