dc.description.abstractTwo forms of spread-spectrum signaling: direct-sequence and hybrid (direct-sequence/ frequency-hopped) are shown to provide high broadcast capability especially when used in conjunction with forward-error-control coding schemes. The broadcast capability is defined as the maximum number of simultaneous distinct messages that can be transmitted to distant receivers from a single transmitter at a given bit-error-rate. This quantity provides a useful measure of the capacity of hub-to- mobile or satellite-to-earthstation links of communication networks. When bursty data or voice traffic is dominant in such networks, the above forms of spread-spectrum code-division multiple-access (CDMA) provide a viable alternative to frequency- division (FDMA) or time-division (TDMA) multiple-access.en_US
