5920594 Transversal filter capable of processing an input signal of high data rate July 6, 1999
In a transversal filter for filtering an input signal (IN) into an output signal (OUT) in response to first through third tap gains (C.sub.-1, C.sub.0, C.sub.1), the transversal filter comprises a serial-parallel converter (40) for converting the input signal into first and second pa
5880629 Demodulator having variable gain amplifier and A/D converter controlled by signal level March 9, 1999
The demodulator of this invention is directed toward improving S/N ratio of the demodulator resulting from increase in the peak value of a received signal due to fading. The demodulator is composed of a roll-off filter (not shown), variable amplifier 16, multiplier 10, compressor 11, var
5793806 Transversal filter capable of processing an input signal high data rate August 11, 1998
In a transversal filter for filtering an input signal (IN) into an output signal (OUT) in response to first through third tap gains (C.sub.-1, C.sub.0, C.sub.1), the transversal filter comprises a serial-parallel converter (40) for converting the input signal into first and second pa
5075697 Dual polarization transmission system December 24, 1991
A dual polarization transmission system for transmitting digital modulated signal each having a particular bandwidth by use of two polarized waves which have the same center frequency and are orthogonal to each other. The receiver side of the system demodulates radio frequency signals se
4870646 Word synchronizer September 26, 1989
For establishing word synchronization between a data bit stream of N-bit words and the timing of syndrome calculation, a count value is incremented in response to the bit timing of the words and generating a hunting pulse for every count of N bits and a load timing pulse at every count o
4811021 Dual polarization transmission system March 7, 1989
A dual polarization transmission system includes a first circuit for alternately arranging a plurality of channels having a first bandwidth on a first polarized wave and a second polarized wave orthogonal to the first polarized wave on a frequency axis, and a second circuit for alternate
