The DVI Adaptive Differential Pulse Code Modulation (ADPCM) algorithm was first described in an IMA recommendation on audio formats and conversion practices [1]. ADPCM is a transformation that encodes 16-bit audio as 4 bits (a 4:1 compression ratio).

the OFDM PHY is adaptive therefore it supports multiple schemes BPSK, QPSK, 16-QAM and 64-QAM for data carriers’ modulation. The constellation diagrams are gray mapped and shows the magnitudes I and Q (In-phase and Quadrature) components of e
