Abstract

Different from other Coding, based on the Overlapped Multiplexing Principle discovered by author, a novel OVTDM (Overlapped Time Division Multiplexing) Waveform Coding is proposed. Instead of the encoding matrix and mapped signal constellation, any engineering sense band-limited Multiplexing Waveform can be employed. By its data weighted shift overlapped versions, the coding gain and spectral efficiency are both achieved. The heavier the overlap of the data weighted Multiplexing Waveform, the higher the coding gain and spectral efficiency as well as the closer the output to the optimum complex Gaussian distribution. The encoder structures, parameters, optimum and fast decoding algorithms, pre-coding, some implementation problems as well as the bit error performance are estimated and discussed. Simulations show that OVTDM is suitable for high spectral efficiency applications and its spectral efficiency is roughly proportional to SNR.
