An FH binary orthogonal FSK system employs an m 15 stage liner feedback shift register that generates an ML sequence. Each state of the shift register selects one of L non over lapping frequency bands in the hopping pattern. The bit rate is 100 bits/s. The demodulator employ non coherent detection. Suppose the hop rate is increased to 2 hops/bit and the receiver uses square law combining the signal over two hops. The hopping bandwidth for this channel is? |
A. | 3.2767 MHz |
B. | 13.1068 MHz |
C. | 26.2136 MHz |
D. | 1.6384 MHz |
Answer» C. 26.2136 MHz | |
