A Truncated Orthogonal Chirp Division Multiplexing Based Communication System
In this work, we propose a non-orthogonal chirp multi-carrier system termed as truncated orthogonal chirp division multiplexing (TOCDM), which uses time-domain truncation to reduce the number of transmitted samples, thereby enhancing spectral efficiency. Compared with the existing truncated orthogonal frequency division multiplexing (TOFDM), TOCDM is more resistant to interference caused by truncation due to the use of chirp. A comprehensive description of the TOCDM system model is given, along with an analysis of inter-carrier interference (ICI) caused by truncation. Simulations demonstrate the superiority of the TOCDM over existing TOFDM in both spectral efficiency and transmission performance.
