DUAL-MODE FM/CDMA COMMUNICATION SYSTEM |
摘要 |
A dual-mode digital communication system for communicating an information signal during operation in frequency-modulated (FM) and multiple-access modes is disclosed herein. The digital communication system includes a dual-mode transmitter (14) for transmitting the information signal using an FM communication signal during FM mode operation, and for transmitting the information signal using a multiple-access communication signal during multiple-access mode operation . The communication system further includes a dual-mode receiver (16) for receiving the FM communication signal during FM mode operation, and for receiving the multiple-access communication signal during multiple-access mode operation. Incorporated within the dual- mode receiver (16) is a digital demodulator (96) for recovering the information signal from the received FM signal during operation in the F M mode, and for recovering the information signal from the received multiple-access signal during multiple-access mode operation.</SDOA B>
