Реферат: The disclosed systems, structures, and methods are directed to a spectrally-efficient orthogonal code generation architecture. The configurations presented herein employ a full-set code generation module configured to generate a candidate code group, wherein the candidate code group contains 2 L different codes for a given code length L, a frequency response calculation module configured to calculate frequency response of the codes within the candidate code group and a frequency code searching module configured to search the orthogonal codes within each frequency code group. In addition, the grouping of codes is done on the basis of number of frequency locations and positions, one or more code sets are formed within each frequency code group, codes within code sets are orthogonal in nature and orthogonal codes along with their identifier information are stored in a database forming an orthogonal code list.
