OFDM modulation is widely used in several communications systems. An advanced modulation scheme, called OFDM/OQAM with IOTA pulse shaping has been identified as one potential method to enhance the performance of these systems. Nevertheless, the IOTA filtering increases the architecture complexity. Moreover, for high-throughput communication of the order of about of hundreds of MHz, we showed that pipelined FFT architecture combined with IOTA filter are not area and power-efficient coarse-grained configurable architecture using parallel architecture and combined with pipelined strategy, offers a better tradeoff between scalability, performance and low power.
