of OFDM symbols with either the data from the first data pipe y0y1y2y3, using a lower order modulation scheme 94 (e.g. M-QAM), or the data form the first data pipe and the local service insertion data pipe h0h1, using a higher order modulation scheme 96 (e.g. at least 2M-QAM)...
Multilevel modulation methods are basically classified based on carrier‐based modulation (CBM) and space vector modulation (SVM). Both of these modulations belong to the same family of pulse﹚idth modulation. SVM is heavily dependent on the computational calculations; hence, there is no need to ...
