In this paper, we propose an area and power efficient pipeline FFT processor for 8×8 MIMO-OFDM systems. The proposed FFT processor is based on mixed-radix multipath delay commutator (MRMDC) architecture in terms of low complexity and high memory utilization. A conventional MRMDC FFT processor increases hardware scale due to delay commutators which are used to change the order of the input sequences. The proposed FFT processor employs pre- and post-commutators which can reduce delay elements and… CONTINUE READING
