A SIMPLIFIED DIGITAL FIR FILTER FOR DIRECT SEQUENCE SPREAD SPECTRUM COMMUNICATION SYSTEMS |
| 摘要 |
<p>A spread spectrum modulated signal generator is disclosed that reduces the storage requirement for storing values representing filter responses of input signal samples in a digital filter by taking advantage of time-reversal symmetry of the responses. Moreover, the disclosed signal generator supports up-ramping and down-ramping for smooth transmission of spread spectrum modulated signals.</p> |
