coherent detection

Coherent orthogonal binary FSK modulation is used to transmit two equiprobable symbol waveforms $${s_1}\,(t)\, = \,\alpha \,\,\cos \,\,\,2\,\pi {f_1}\,t\,and\,\,{s_{2\,}}(t)\,\, =...

If S represents the carrier synchronization at the receiver and $$\rho $$ represents the bandwidth efficiency, then the correct statement for the coherent binary PSK is

For a bit-rate of 8 kbps, the best possible values of the transmitted frequencies in a coherent binary FSK system are

In a BPSK signal detector, the local oscillator has a fixed phase error of 20 0 . This phase error deteriorates the SNR at the output by a factor of

In binary data transmission DPSK is preferred to PSK because
