| description | OFDM receiver needs a channel equalizer (CE) to gain similarity between
received signals and transmitted signals. CE multiplies received signal with a
weighting factor which results a signal similar with transmitted signal. Weighting
factor is reciprocal of the channel estimator output, which become the multiplier
factor in CE.
This research offered a reciprocal circuit to process the output from estimator
and interpolator blocks yield OFDM CE weighting factor. There are two reciprocal
circuit designs in this research. They are reciprocal without internal bit scaling
(system A), and reciprocal with internal bit scaling (system B). Reciprocal circuits
in this research is four sub-channels circuit, with sequential multiplier and
sequential divider. The circuits are designed with VHDL (Very high speed
integrated circuit Hardware Description Language) and Xilinx ISE 12i sofware.
Design result and simulation show that system A needs 2,279 slices of FPGA
resource and 609.876 ns delay. In the other hand, system B needs 1,136 slices of
FPGA resource and 262.06 ns delay. |
