Exact BER Calculation of Asynchronous DS-CDMA Systems Communicating over Hoyt Channels [PDF]

open access: yes, 2006
An asynchronous binary DS-CDMA system using random spreading sequences is considered in flat Hoyt fading channels. A new closed-form expression is derived for the conditional characteristic function of the multiple access interference.
