Abstract EN
A prototype filter design for FBMC/OQAM systems is proposed in this study.
The influence of both the channel estimation and the stop-band energy is taken into account in this method.
An efficient preamble structure is proposed to improve the performance of channel estimation and save the frequency spectral efficiency.
The reciprocal of the signal-to-interference plus noise ratio (RSINR) is derived to measure the influence of the prototype filter on channel estimation.
After that, the process of prototype filter design is formulated as an optimization problem with constraint on the RSINR.
To accelerate the convergence and obtain global optimal solution, an improved genetic algorithm is proposed.
Especially, the History Network and pruning operator are adopted in this improved genetic algorithm.
Simulation results demonstrate the validity and efficiency of the prototype filter designed in this study.
