초록 ▼

A high-capacity-spread-spectrum transmitter and receiver, for use over a communications channel. A demultiplexer demultiplexes message data into a plurality of demultiplexed-data signals. A transmitter-generic-chip-code generator generates a generic-chip-code signal and a plurality of transmitter-message-chip-code generators generate a plurality of message-chip-code signals which are “near-orthogonal”over a demultiplexed data bit. A plurality of EXCLUSIVE-OR gates, spread-spectrum processes the plurality of demultiplexed-data signals with the plurality of message-chip-code signals to generate a plurality of spread-spectrum signals. A combiner combines the generic-chip-code signal and the plurality of spread-spectrum-processed signals. A receiver-generic-chip-code generator generates a replica of the generic-chip-code signal. A generic mixer recovers the carrier signal from the spread-spectrum-communications signal. A plurality of receiver-message-chip-code generators generate a plurality of replicas of the message-chip-code signals. A plurality of message mixers despreads the spread-spectrum-communications signal as a plurality of modulated-data signals. Tracking and acquisition circuits use the recovered carrier signal for synchronizing the replicas of the generic-chip-code signal to the recovered carrier signal. A plurality of envelope detectors demodulates the modulated-data signal as a plurality of received-demultiplexed data. A multiplexer multiplexes the plurality of received-multiplexed data as received data.

대표청구항 ▼

A high-capacity-spread-spectrum transmitter, handling at least spread-spectrum-signals for use with a communications channel, comprising: demultiplexer means for demultiplexing message data into a plurality of demultiplexed-data signals; generic means for generating a generic-chip-code signal; a plurality of message means for generating a plurality of message-chip-code signals, wherein each message-chip-code signal is orthogonal to the other message-chip-code signals of plurality of message-chip-code signals, and is synchronized to the generic-chip-code signal; a plurality of spreading means coupled to said demultiplexer means and said plurality of message means, respectively, for spread-spectrum processing the plurality of demultiplexed-data signals with the plurality of message-chip-code signals to generate a plurality of spread-spectrum-processed signals, respectively; summer means for combining the generic-chip-code signal with the plurality of spread-spectrum-processed signals; transmitter means for transmitting the combined generic-chip-code signal and plurality of spread-spectrum-processed signals, on a carrier signal over said communications channel as a spread-spectrum-communications signal.
