【Abstract】 The capacity and bandwith efficiency of direct sequence spread spectrum (DS)sys-tem with Rake receiver are considered.A Rayleigh fading,discrete muitipth model is used.The focus of this paper is on the effect of spread spectrum sequence lengh,number of termsused for Rake and narrow band interference on the capacity and bandwith efficiency.更多还原
