Abstract

A spread-spectrum receiver for receiving data from a spread-spectrum packet-swioched system. A multichannel spread-spectrum signal includes encoded data, which is demultiplexed into sub-data-sequence signals. Each sub-data-sequence signal is multiplied by a respective chip-sequence signal to generate a plurality of spread-spectrum channels. The plurality of spread-spectrum channels are combined as a multichannel spread-spectrum signal. The multichannel spread-spectrum signal is concatenated with a header to output a packec-spread-spectrum signal which is transmitted over radio waves to a packet receiver. A processor at the packet receiver obtains ciming for the multichannel spread-spectrum signal from the header. The multichannel spread-spectrum signal is chen despread by a plurality of data-matched filters and multiplexed by a multiplexer as received-encoded data. The received-encoded data is decoded by a decoder and stored in a receiver memory for output.
