Variable-Length Orthogonal Codes over Finite Fields Realizing Data Multiplexing and Error Correction Coding Simultaneously

DOI Web Site

抄録

<p>The present study proposes a scheme in which variable-length orthogonal codes generated by combining inverse discrete Fourier transform matrices over a finite field multiplex user data into a multiplexed sequence and its sequence forms one or a plural number of codewords for Reed-Solomon coding. The proposed scheme realizes data multiplexing, error correction coding, and multi-rate transmitting at the same time. This study also shows a design example and its performance analysis of the proposed scheme.</p>
