Hi
As euclidean distance between two points is sqrt((x2-x1)^2+(y2-y1)^2 ) i.e distance between two points.
What is "product distance" and "sum distance" ? what these terms means and how to calculate product distance of a QAM constellation?
Thanks
Hi
I have a basic question regarding Constellation designing criteria.
What are the constraints while designing a good constellation ?
Like What is the cost of increasing the dimensions?
How to select the coordinates in case of 2 dim (e.g in QAM (1,1) or (1/sqrt2,1/sqrt2) whats the effect)...
Hi
Anyone please help me how to construct multiple codebooks for SCMA? The first step is to design a multidimensional constellation. But how to construct the codebooks from mother constellation using operators like phase rotation, conjugate and permutation operators? I am trying to implement...
Hi
How binary symbols are mapped to multidimensional constellation points? Like in APSK symbols are mapped to constellation points of different Phase and Amplitude.
And what is the "shaping gain" ?
Thanks
