The characteristics of the 2D spreading based communication systems
Jiří Blumenstein, Zbynek Fedra · 2009
This paper deals with characteristics and theory of code division multiple access (CDMA), orthogonal frequency division multiplexing (OFDM) and variable spreading factor orthogonal ferquency and code division multiplexing (VSF-OFCDM) systems. As comparison and evaluation of VSF-OFCDM with various 2D spreading factor (SF) as frequency and time dispersive transmission channel according to ETSI standard (typical rural area and warehouse enviroment) is being done.
