Abstract: The present invention provides a method of minimizing synchronization delay in a radiotelephone system between a modular subscriber cluster communicating with a common base station, the modular subscriber cluster receiving repetitive time slots from the base station and having a plurality of frequency-agile modems, the method comprising the steps of:
synchronizing a selected one of the modems to a selected time slot of the received time slots;
generating a frame sync signal from said selected modem; and distributing said frame sync signal to remaining ones of the plurality of modems.

Abstract: A plurality of data streams are convolutionally encoded. Each convolutionally encoded data stream has a particular data rate. The particular data rate of each data stream is adjusted so that an adjusted data rate of that data stream matches a data rate of a CDMA transmission. When the particular data rate of one of the data streams is below the data rate of the CDMA transmission, data of the one data stream is repeated to match the data rate of the CDMA transmission. The adjusted data rate data streams is transmitted as the CDMA transmission. The adjusted data streams are transmitted together in the CDMA transmission and the CDMA transmission is quadrature modulated.
