2007年8月30日 · Simple transmit-receive block diagram for binary frequency shift keying (FSK) can be as shown below. Figure: Block diagram of FSK modulation and coherent demodulation. For analyzing the bit error rate with coherent FSK demodulation, let us compare the signaling waveform used by binary FSK when compared with binary PSK. The distance between the ...

The fraction of all bits that are in error is called the bit error rate or BER. The BER is the same as the probability that a given bit will be in error, which we write as Pe. The BER will depend on the choice of modulation (amplitude, phase, frequency) that we use to send m (t ) . The modulation scheme will also affect the required RF bandwidth.

A relay network adopting noncoherent frequency shift keying (FSK) is considered. We begin by deriving the exact closed-form BER expression for M-ary FSK (MFSK) with perfect frequency synchronization and then obtain the exact BER with a triple integral for MFSK with imperfect frequency synchronization.

BFSK (Binary FSK) Modulation: Transmits one of two signals: +√Eb ( On the y-axis, the phase shift of 90 degrees with respect to the x-axis, which is also termed phase offset ) or √Eb (on x-axis), where Eb is the energy per bit.

Minimum shift keying (MSK) is specific case of continuous phase frequency shift keying (CPFSK) where the peak frequency deviation is one half the bit rate. The characteristics of MSK include constant envelope, spectrally efficient suppression of …
