A system and method for encoding and transmitting data with a spread-spectrum
packet-switched
system. Data to be transmitted by a packet transmitter are encoded for privacy
and to restrict intelligent receipt of the data to the intended recipient. The
encoded data is demultiplexed into sub-data-sequence signals which are spread-spectrum
processed and then combined as a multichannel 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-encoded
data. The received-encoded data is decoded by the intended recipient and stored
in a receiver memory for output.
