Area-efficient FFT processor for MIMO-OFDM based SDR systems
In this letter, an area-efficient FFT processor is proposed for MIMO-OFDM based SDR systems. The proposed FFT processor can support variable lengths of 64, 128, 256, 512, 1024, 1536 and 2048. By reducing the required number of non-trivial multipliers with a mixed-radix algorithm, the complexity of the proposed FFT processor is dramatically decreased. The proposed FFT processor was designed in a...

متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Design of Area- and Power-Efficient Pipeline FFT Processors for 8x8 MIMO-OFDM Systems
We present areaand power-efficient pipeline 128and 128/64-point fast Fourier transform (FFT) processors for 8x8 multipleinput multiple-output orthogonal frequency multiplexing (MIMO-OFDM) systems based on the specification framework of IEEE 802.11ac WLANs. Our new FFT processors use mixed-radix multipath delay commutator (MRMDC) architecture from the point of view of low complexity and high mem...
متن کاملHigh-Speed Four-Parallel 64-Point Radix-2 MDF FFT/IFFT Processor for MIMO-OFDM Systems
This paper presents a design and implementation result of a high-speed, low-complexity four data-path 64point radix-2 FFT/IFFT processor for high-throughput MIMO-OFDM wireless LAN system. The proposed FFT/IFFT processor can provide a higher throughput rate and low hardware complexity by using a four-parallel datapath scheme and a multipath delay feed-back (MDF) structure. The proposed four data...
