- W2370032300 abstract "The channel estimation techniques for OFDM systems based on pilot-aided arrangement are investigated. The MMSE algorithm could obtain good performance,but with high complexity. The LS algorithm has low complexity, while its performance is not sufficiently satisfying. In comprehensive consideration of performance and computational complexity,two simplified estimators for LS and MMSE are proposed. Simultaneously,the shortcomings of the second order interpolation based on comb-type pilot is analyzed,and a modified algorithm for the second order interpolation presented. The simulation results show that the modified second order interpolation performs better than original interpolation algorithms." @default.
