“…DA relies on the fact that the filter coefficients 𝑐[𝑛] are known, so multiplying 𝑥[𝑛]𝑐[𝑛] becomes a multiplication with a constant. This is an importance difference and a prerequisite for a DA design [11][12]. DA uses Lookup Table (LUT) to store the pre-computed result to reduce computational complexity.…”

A higher data rate with lower intersymbol interference (ISI) and intercarrier interference (ICI) are the main features provided by Filter bank multi-carrier (FBMC) modulation technique to be the most candidate for 5G wireless networks. Although the different advantages of FBMC systems, it suffers from the higher power consumption and complexity of the structure, as a result of using fast Fourier transform/ inverse fast Fourier transform (FFT/IFFT) processors with a high order polyphase filter network in both transmitter and receiver. This paper presents a complete analysis, design, and implementation of a proposed low power FBMC transceiver architecture for a different number of multi-users or subscribers. The suggested method aims to reduce power consumption and area resources by reducing the complexity of the FFT (2 𝑛 Points) processor by using a feedback loop with a (𝑛) points FFT core. Also, the design of FIR filters is based on distributed arithmetic (DA) algorithm in which all multiplications and additions are replaced by a table and a shifter. The design and implementation are done using a Xilinx system generator tool and spartan-6 field programmable gate array (FPGA) board. The proposed implementation method presents a reduction in resources by 15 % compared to conventional implementation.
