On Throughput Optimization of OFDM System with Variable Cyclic-Prefix Length over Two-Path Channel Model
Masaya Arakawa, Hideki Ochiai (YNU) RCS2018-237
Abstract (in Japanese) (See Japanese page) 
(in English) Orthogonal frequency-division multiplexing (OFDM) generally gains
its resistance against channel delay spread by insertion of cyclic-prefix (CP).
In principle, the inter-symbol interference (ISI)
can be avoided provided that the CP length is longer than
that of the channel delay spread. However, the delay spread
is not known {em a priori} in general, and increase of CP length
also decreases the spectral efficiency.
In our previous work, we have investigated the optimum CP length
that maximizes the throughput for OFDM system with variable CP length.
In this work, we theoretically analyze the optimum CP length
over two-path Rayleigh fading channel model.
