Performance of Baseband-Bandlimited Multilevel FM with Discriminator Detection for Digital Mobile Telephony
Summary :
Performance of multilevel FM with discriminator detection is studied for digital speech transmission in mobile radio channels. New transmit- and receive-baseband filter configurations in digital FM are considered. The low-pass filters are characterized by a square root of the raised cosine Nyquist filter. The present method is simple as an analog FM and has high immunity against fast fading. It is shown that digital speech can be transmitted with a 4-level FM and a 16 kbit/s adaptive delta modulation under a 25 kHz channel spacing, where the relative interchannel interference power is around -70 dB.
