Design of Reconfigurable OFDM and CDMA Transceiver Based On FPGA
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
The rapid expansion in digital Wireless communications results in a demand for systems that are reliable and have a high spectral efficiency. To fulfill these demands, the multicarrier modulation scheme, often called Orthogonal Frequency Division Multiplexing (OFDM), has drawn a lot of attention. On the other hand Code Division Multiple Access (CDMA) techniques have been considered to be a candidate to support multimedia services in mobile radio communications. In this work, Space–Time Block Coding is a technique used in wireless communications to transmit multiple copies of a data stream across a number of antennas and to exploit the various received versions of the data to improve the reliability of data-transfer. The fact that the transmitted signal must traverse a potentially difficult environment with scattering, reflection, refraction and so on and may then is further corrupted by thermal noise in the receiver means that some of the received copies of the data will be better than others.
