This paper proposes a downlink beamforming method in TDD (time division duplex)-type CDMA (code division multiple access) system. The proposed beamforming is a method that can satisfy various requirements of the user for SINR (signal-to-interference-

An ultrawideband (UWB) format that jointly utilizes direct-sequence (DS) and time-hopping (TH) spreading, which is called direct-sequence impulse radio (DS-IR), is analyzed. A simple and widely applicable expression for the symbol error rate (SER) of
