The PAPR and Simple PAPR Reduction of the 2D Spreading Based Communication Systems
MetadataShow full item record
This paper deals with Peak to Average Power Ra- tio (PAPR) characteristics and the theory of variable spread- ing factor orthogonal frequency and code division multiplex- ing (VSF-OFCDM) systems. Comparison and evaluation of PAPR of VSF-OFCDM systems with various 2D spreading factors (SF) are done in time and in frequency domain. The simple PAPR reduction approach based on random chip in- terleaving is also evaluated.
