This paper proposes a software radio receiver which utilizes an RF filter bank in the front end and optimally combines the signals whose bandwidth is divided by the filter bank. This method assumes the future solid state advanced integrated circuit technologies in RF filters, RF receiving circuit and A/D converters (ADC). The optimal combining utilizing the multiple input linear equalizer regenerates the wide band signal in baseband from the discrete complex envelopes that are sampled from the outputs of filters constructing the RF filter bank. The equalizer uses chirp signal as the training signal. Time alignment of the complex impulse response to the chirp signal yields the complex impulse response of the combining circuit. The combiner circuit minimizes the difference between the complex impulse response and the desired impulse response, and it becomes the matched filter. Computer simulation is conducted in order to evaluate the reception performance by utilizing Gaussian bandpass filter for the filter bank. Both single carrier roll-off and OFDM multicarrier signals are examined. The simulation shows the dependences of eye pattern and that of bit error rate (BER) upon the number of bits of ADC, and dependence of BER upon an out-of-band interference signal. The results show the superiority of the filter bank receiver to the digital filter receiver. |
