This work considers the problem of enabling maximum multipath diversity of orthogonal chirp division multiplexing (OCDM)-based systems. We define and study an Affine OCDM (A-OCDM) system in which a chirp parameter is adapted to enable maximum diversity offered by frequency selective channels. Our proposed system also reduces implementation complexity by eliminating the need for precoding, compared to linear constellation precoded OCDM. Corroborating simulations are provided to show that A-OCDM also preserves OCDM systems' resilience against interference offered by spreading.
