Diversity receiver

A diversity receiver for a digital modulation wave having a given symbol rate, comprising:

• a first antenna;
• a first receiving section connected to the first antenna for converting a digital modulation wave induced at the first antenna into a first intermediate-frequency signal;
• a first band pass filter connected to the first receiving section for subjecting the first intermediate-frequency signal to a band pass filtering process;
• a second antenna;
• a second receiving section connected to the second antenna for converting a digital modulation wave induced at the second antenna into a second intermediate-frequency signal;
• a second band pass filter connected to the second receiving section for subjecting the second intermediate-frequency signal to a band pass filtering process;
• switch means for alternately selecting one of output signals of the first and second band pass filter at a period equal to a half of a period corresponding to the symbol rate;
• a quadrature demodulator connected to the switch means for demodulating an output signal of the switch means into quadrature baseband signals;
• an analog-to-digital converter connected to the quadrature demodulator for converting the quadrature baseband signals into corresponding digital signals;
• and
• a decision feedback adaptive equalizer connected to the analog-to-digital converter for subjecting the digital signals to an equalizing process.
