Minimum number of crossed channels for OFDM systems based on regular interconnections
Josef Giglmayr · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
For OFDM systems based on multistage interconnection networks with space-frequency interstage patterns the number of crossed channels and the interconnection length in the frequency domain is aimed to be a minimum. A solution which only requires nearest-neighbor interconnections in the frequency domain is proposed and discussed.
