A buffer apparatus comprises a data symbol library (370) communicating with the signal input structured to match the communication signal with a stored data symbol, a first radio frequency waveform library (380) communicating with the data symbol library structured to match the stored data symbol with a stored digital radio frequency waveform and a digital to analog converter (DAC), communicating with the first radio frequency waveform library structured to convert the digital radio frequency waveform to an analog signal. |
