| Abstract: |
| A general space-time CDMA system model in multipath fading channels is built to study how to suppress both multiple access interference (MAI) and multipath fading. Identification conditions are first studied. Then a FIR solution of space-time decorrelating receivers is implemented by an optimal criterion with multiple constraints and system performances are analyzed. |
