| Summary: | SC-FDMA is a multiple-access technique which is a modified version of
OFDMA OFDMA is a multicarrier multiple-access technique which is able to
provide parallel transmission service with high bit rate and very efficient in
bandwidth usage and used in LTE downlink. SC-FDMA designed to minimize
OFDMA�s weakness in power efficiency, so it suitable to be implemenedt in LTE
uplink.
The objective of this study is to implement a model of SC-FDMA transmitter
on a Xilinx Spartan-3E FPGA chip. Design is divided into sections that include QPSK
mapper, FFT, IFFT, and parallel to serial converter. The design is created with
VHDL in Xilinx ISE 9.2i software. The output of SC-FDMA transmitter is displayed
on LCD interface on Xilinx Spartan-3E development board and compared with output
of similar SC-FDMA transmitter modeled in Excel and Matlab.
As a result, the implementation of SC-FDMA transmitter is able to show true
performance and very close to the result of Matlab. In terms of capacity, Xilinx
Spartan-3E FPGA is sufficient for the needs of the design. |
