We propose an improved adaptive algorithm for blind channel equalization based on chirp modulation. Our method utilizes an improved objective function that removes ISI and amplifies signal gain simultaneously. An optimal weighting factor is also derived for the balance between ISI and signal gain. It turns out that our method exhibits better performance since the original chirp modulation based adaptive algorithm considers only ISI removal and thus fails to improve performance in SIMO channel. The simulation results confirm the superiority of proposed algorithm over the original one in both SISO and SIMO channels. The steady state performance of our method is also close to another chirp modulation based batch algorithm in SIMO case.
