PSSS Design for Efficient Equalization

Abstract

Parallel sequence spread spectrum (PSSS) is a novel physical layer (PHY) technique allowing a flexible resource allocation through code multiplexing. This broadband technique is designed for high data rates in industrial applications, as it offers benefits in fading environments at a relatively low hardware complexity. In this paper we compare different approaches for the equalization of wireless channels in a PSSS communication system. For this purpose we employ multiple baseband impulse responses representing diverse transmission conditions. We analyze the performance of the cyclic prefix based PSSS design from previous work and compare it with our more efficient equalization approaches.
