Abstract

Wireless home theater and speaker system was designed. That has 20W output per channel, 0.1% THD (Total Harmonic Distortion) and automatic algorithm avoiding noise. The 3D stereophonic sound was realized through the wireless 5.1channel speaker system designed. That could be secured 0.4% improvement effect of THD compared with wire speaker systems. Specially in transfer sound with wireless, Frequency Hopping Spread Spectrum was superior than Direct Sequence Spread Spectrum in household electric appliances and wireless internet environment that radiated noise similar with ISM Band using 2.4GHz.
