Abstract:
1. A method for high density pulse density modulation, comprising: receiving a bitstream; splitting the bitstream in to two complementary streams based on whether a modulation level exceeds a limiting value v, wherein a first one of the two complementary streams contains a soft clipped stream of the received bitstream limited by the limiting value v, and a second one of the two complementary streams contains only extracted portions of the received bitstream, wherein when a portion of the received bitstream is greater than v, said portion of the received bitstream is represented based on a difference of said portion of the received bitstream and the limiting value v in the second one of the two complementary streams, and wherein when a portion of the received bitstream is less than −v, said portion of the received bitstream is represented based on a sum of said portion of the received bitstream and the limiting value v in the second one of the two complementary streams; and amplifying each of the two complementary streams independently for transmission.
