Constrained optimization applied to pulse compression codes and filters

The purpose of this paper is to give the reader an understanding of the expected results when using constrained optimization to find codes that are optimized for auto correlation ISL, auto correlation PSL, mismatch filter ISL and mismatch filter PSL. Concentrating mainly on 32 chip codes, this paper tries to give a feel for the depth and breadth of possibilities for finding different pulse compression codes and filters. A framework is defined within the performed optimization. Various results including example codes and numbers of expected codes for various sizes indicating abundance are presented.
