Addition Theroem to Allow More Complicated Radiation Patterns

(A and B) Two typical addition processes of 2-bit complex codes for ${\dot{0}}_2+{\dot{1}}_2={\dot{1}}_3$ (A) and ${\dot{0}}_2+{\dot{3}}_2={\dot{7}}_3$ (B) on the coding circle.

(C–E) Coding schemes and their 3D and 2D scattering patterns calculated by FFT to illustrate the influence of indefinite coding addition.

(C) The coding sequence 00110011··· along the x-direction.

(D) The coding sequence 00110011··· along the y-direction.

(E) The addition of the coding patterns in (C) and (D) using the new coding scheme by correcting the indefinite coding elements.

(i) Coding patterns. (ii) 3D radiation patterns. (iii) 2D radiation patterns.
