Title: Center error detecting circuit for fsk receiver
Inventor: KAWAI KAZUO
IPC: H04L27/14
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To realize a detecting circuit whereby an offset component is easily detected and corrected at high speed against an incoming signal since the demodulation baseband of a bit synchronizing signal by FSK(frequency shift keying) is normally transmitted in a wide band to be sine wave and also frequency error is superimposed with the sine wave as a DC offset so that the DC offset becomes a bias distortion against a transmission code. SOLUTION: The bit synchronizing signal in the baseband is the sine wave of 4800bps when data rate is 9600bps and the sine wave is repeated with 1/4800sec as one cycle, that is, 360 deg.. Then, difference in an instantaneous phase angle between two time points separated by 1/9600sec is 180 deg. so that two sample values separated by 1/9600sec in the signal are normally positioned to be symmetrical against a center level. This means that the average value of the two sample values corresponds to the center level so that a circuit for obtaining the average value of the two sample values at the two time points separated by 1/9600sec is constituted.
