Across
- 2. bandwidth occupied by FSK
- 3. transmission have better noise immunity
- 4. sequence of the large bandwidth is multiplied with narrow band data signal
- 5. noise sequence is a noise like high frequency signal
- 6. communication systemms more flexible
- 7. are repeated symbols
- 9. gain is the ratio of spreaded signal bandwidth to unspreaded signal bandwidth
- 10. probability of DPSK is higher than that of BPSK
Down
- 1. Bandwidth of BPSK system is 2fb
- 2. and processing becomes easier due to digital communication
- 6. requires wide band channel with small phase distortion
- 8. spectrum makes antijam
