Abstract |
|
OFDM is multicarrier technique, which is efficient due to its orthogonality. It uses FFT/IFFT processors for modulation and demodulation purpose. FFT/IFFT is computationally complex with wide length data and time consuming task. So the processing time can be reduced which will result into increase in the throughput of the system. This paper reviews various multiplier techniques used for FFT processor. However by simulating different multipliers and analysing performance parameters of multipliers such as memory, delay and I/O buffers, Dadda multiplier is best suited for DSP applications. |
