Abstract
A system and method for encoding and transmitting data with a spread-spectrum time-division-multiple-access (SS-TDMA) system. Data to be transmitted by a SS-TDMA transmitter are sent within a particular specified group of time slots. Random packets also can be sent by transmission during an open time slot. The TDMA data are demultiplexed into sub-data-sequence signals, each of which are spread-spectrum processed and then combined as a multichannel, BPSK, QPSK or QAM spread-spectrum signal. The multichannel spread-spectrum signal is concatenated with a header to output a packet-spread-spectrum signal which is transmitted over radio waves to a packet receiver. The packet receiver obtains timing for the multichannel spread-spectrum signal from the header. The multichannel spread-spectrum signal is then despread and multiplexed as received-TDMA data. The received-TDMA data are selected from a particular time slot by the intended recipient and stored in a receiver memory for output.
