| Abstract: | A new modulated lapped biorthogonal transform (MLBT) with optimized windows was introduced for non-orthogonal multi-tone interference cancellation in spread spectrum communications. The bit error rate (BER) expression of the receiver employing the proposed MLBT excision-based algorithm was derived and its performance was compared with that of the modulated lapped transform (MLT) excision-based receiver. The simulation results show that the lapped biorthogonal transform domain excision technique is capable of improving system performance and enhancing the robustness of the receiver. |
| Keywords: | spread spectrum communications modulated lapped biorthogonal transform (MLBT) narrowband interference suppression |
