AN OPTIMUM RAKE RECEIVERS APPROPRIATE FOR IMPULSIVE ENVIRONMENT WITH REDUCED COMPLEXITY

摘要

A rake receiver which is optimum for impulse noise and has a simple structure is provided to lead an optimum rake receiver on the basis of the most similar property on an impulsive noise attenuation channel, and to obtain a quasi-optimum rake receiver showing optimum performance in case of weak signals, thereby simplifying a structure of the receiver. A rake receiver is provided on the basis of an equation 15 or 16. The rake receiver based on the equation 15 should estimate signal strength, while the rake receiver based on the equation 16 does not have to estimate the signal strength. Compared to the rake receiver based on the equation 15, the rake receiver based on the equation 16 has a simpler structure.
