Performance Evaluations of DCT Interpolation-Based Channel Estimation Method for MIMO-OFDM System

摘要

This letter proposes to employ the Discrete Cosine Transform (DCT) interpolation-based channel estimation (DCTI-CE) method for practical MIMO-OFDM (Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing) system so as to achieve its potential ability for enabling high transmission data rate. The various computer simulations are conducted to evaluate the DCTI-CE method in MIMO-OFDM system under the multipath fading channel for wireless LANs.
