A autocorrelação de sequências de período parcial é uma importante medida de desempenho dos sistemas de comunicação que as empregam, mas é notoriamente difícil de ser analisada. Neste artigo, propomos um algoritmo para projetar sequências unimodulares com baixas autocorrelações de período parcial através da minimização direta do nível de lóbulo lateral integrado de período parcial (PISL). O algoritmo proposto é inspirado no algoritmo minimizador monotônico para nível de lóbulo lateral integrado (MISL). Em seguida, um esquema de aceleração é considerado para acelerar ainda mais os algoritmos. Experimentos numéricos mostram que o algoritmo proposto pode efetivamente gerar sequências com menor nível de lóbulo lateral de pico de período parcial (PPSL) em comparação com as conhecidas sequências de Zadoff-Chu.

Abstract: The partial-period autocorrelation of sequences is an important performance measure of communication systems employing them, but it is notoriously difficult to be analyzed. In this paper, we propose an algorithm to design unimodular sequences with low partial-period autocorrelations via directly minimizing the partial-period integrated sidelobe level (PISL). The proposed algorithm is inspired by the monotonic minimizer for integrated sidelobe level (MISL) algorithm. Then an acceleration scheme is considered to further accelerate the algorithms. Numerical experiments show that the proposed algorithm can effectively generate sequences with lower partial-period peak sidelobe level (PPSL) compared with the well-known Zadoff-Chu sequences.
