Custom signal data generation in a radio system

A method, comprising:

• selecting, by a system comprising at least one processor, a first signal from,
• a memory that is configured to store and retrieve a second signal,
• a generator that is configured to generate first in-phase, quadrature sub-carrier values,
• a look up table that stores predetermined second in-phase, quadrature sub-carrier values, and
• a pseudo-random look up table generator that is configured to operate on the predetermined second in-phase, quadrature sub-carrier values to produce a pseudo-random symbol of data values;
• injecting, by the system, the first signal into a radio system;
• reading, by the system, a third signal from the radio system, wherein the third signal is generated based on the first signal;
• and
• determining, by the system, a performance metric of the radio system based on a comparison of the first signal and the third signal.

An apparatus, comprising:

• a radio system;
• a signal generation component configured to generate a first signal, wherein the first signal is separate live-air data;
• a signal insertion component that is configured to insert the first signal into the radio system;
• and
• a performance evaluation component that is configured to evaluate performance of the radio system based on a transformation of the first signal performed by the radio system, to produce a second signal, and wherein the performance evaluation component comprises,
• a reading component that is configured to read the second signal;
• and
• a determination component that is configured to determine a performance metric of the radio system based on a comparison of the first signal and the second signal.
