| titleOfInvention | Cognitive radio software simulation platform and design method based on direct-sequence cdma/uwb |
| abstract | The present invention involves a cognitive radio software simulation platform based on direct-sequence Code Division Multiple Access (CDMA)/ Ultra Wideband (UWB), which comprises a Source module, a UWB Pulse Generator module, a Binary Phase Shift Keying (BPSK) Modulation module, an UWB Channel module, a RAKE module, an Equalizer module, a Judging and Error Rate Calculation module. The design method of said platform includes: (1) inputting a Walsh sequence, whose sequence values are "+1" and "-1", and a bridge function sequence, whose sequence values are "+1", "0" and "-1", as spread spectrum sequences to said constructed simulation system; (2) inputting an m sequence and a bridge function sequence as spread spectrum sequences to said simulation system; (3) using bridge function intelligent coding sequences, which have zero correlation zones and whose bridge function sequence correlation function is constant 0, as the spread spectrum sequences of the system in a multi-user system. The simulation results show that, with increase of the shift parameter, the zero correlation zone becomes larger and larger, and the ability of system anti-multi-access interference also becomes stronger and stronger; when using bridge function intelligent coding sequences whose correlation function is constant 0, the ability of anti-multi-access interference achieves the best. |
