  abstract={As bandwidth is becoming precious, spectral efficiency is nowadays one of the key parameters of mobile radio communications. To reach high spectral efficiency in Code Division Multiple Access systems, combating multi-user interference is inevitable. Especially in an uplink scenario this can be done by applying multi-user detection. This paper compares two multiplexing schemes for pilot data in a system with combined maximum likelihood channel estimation (MLCE) and successive interference cancellation (SIC). 	It is shown that even though preceding pilots deliver a better initial channel estimate a scheme with IQ-mapped pilots leads to better performance when using a combined MLCE-SIC receiver.},
