Multiple access (spread spectrum, time-varying filters).

802.11b introduced high rate direct sequence spread spectrum (HR/DSSS).

The invention is applicable to spread spectrum digital communications.

The invention is applicable to spread-spectrum digital communications.

The invention is applicable to digital transmissions with spread-spectrum.

A method of receiving signals in spread spectrum communication.

The module (114) for controlling the phase of the spread-spectrum-modulated light beams is dependent upon the backreflected light signal (126) and the spread spectrum modulation.

A spread-spectrum transmitter and receiver using code division multiple access with time division multiple access technology for spread-spectrum communications.

Modulator and demodulator for spread spectrum systems.

A low power spread spectrum transceiver capable of preserving power while selectively initiating data transmissions under a preferred spread spectrum protocol.

A spread-spectrum location and tracking system, is provided in which the vehicle (10) or object to be located emits a continual direct sequence spread spectrum radio signal (11).

Spread-spectrum frequency modulation is also available to lower EMI levels further.

The transmitter transmits data over a spread-spectrum channel, along with a spread-spectrum channel having little or no information, i.e., an equalization channel to the receiver.

Spread spectrum frequency modulation is also available to lower EMI levels further.
