Alternative Zero Codebooks for MOCZ with Reduced PAPR

Research output: Contribution to journalArticleResearchpeer-review

Abstract

Modulation over conjugate-reciprocal zeros (MOCZ) is a noncoherent modulation scheme proposed for short-packet communication. In this paper, we first derive a closed-form expression for the peak-to-average power ratio (PAPR) of binary Huffman MOCZ. We propose new rotated and skew Huffman zero codebooks by modifying the plain Huffman one. Then we combine the plain, rotated, and skew Huffman zero codebooks to obtain a mixed Huffman MOCZ scheme that yields large savings in PAPR. For an 8-bit mixed Huffman MOCZ with outer radius <italic>R</italic> = 1.1791, a 38% reduction in PAPR is achieved by choosing an angle parameter &#x03B8; = 60&#x00B0; for the 4 bit skew Huffman component.
