Elimination Filter For Co-channel Interference In Asynchronous SSMA Systems
N. Suehiro · 2005
Two classes of orthogonal sequences have been proposed. One is the class of modulatable polyphase orthogonal sequences(l). The other is the class of modulatable real-valued orthogonal sequences(3). A filter for eliminating co-channel interference can be designed for each receivers in the asynchronous SSMA system using the modulated polyphase sequences(2). This filter can be used for eliminating co-channel in- terference in the asynchronous SSMA system using the modulated real-valued sequences.
