This article presents the performance of π/2-shift BPSK modulation scheme used in DS/SS/CDMA wireless communications over multipath Rayleigh fading channel and compares the performance with the performance of conventional BPSK CDMA systems. The performance parameters : Out-of-Band power, average Bit Error Rate(BER) and Spectral Efficiency have been evaluated. In order to obtain improved performance on fading channels, a RAKE receiver has been employed. Finally it is shown that π/2-shiftBPSK outperforms conventional BPSK in the presence of nonlinear amplification.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/7788"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IEEE","subitem_publisher_language":"en"}]},"item_10_relation_8":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"0-7803-4987-3","subitem_relation_type_select":"ISBN"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 1998 IEEE.
