Abstract
A multidimensional symbol encoder is coupled to a transmitter. Multidimensional symbols are encoded by concatenating two or more partial symbols, wherein individual intervals of up and down sections of the two or more partial symbols are independently controlled as to duration. A multidimensional symbol decoder is coupled to a receiver. Multidimensional symbols are decoded by measuring duration of individual intervals i) that are independently controlled as to duration and ii) that are up and down sections of two or more concatenated partial symbols.
