Patent ID: 8457251

Claim:
A direct spatial antenna modulation (DSAM) system comprising: a radiating structure comprising a plurality of spatial points of origination; and a control system, wherein the control system is connected to the radiating structure via N spatial points of origination, wherein N is equal to or greater than 2, and wherein the control system is configured to perform operations comprising: receiving a modulated signal; splitting the modulated signal into N signals; receiving segments of a pseudo-random noise (PN) coded sequence; and for each segment of the PN coded sequence: adjusting an amplitude of each of the N signals in response to the segment of the PN coded sequence; assigning a spatial point of origination to each of the N signals in response to the segment of the PN coded sequence; and simultaneously applying each of the N signals to the assigned spatial point of origination to emit from the radiating structure a radio frequency signal having one of M modulation states, where M is greater than N.
