Patent ID: 8351404

Claim:
A method for multiple transmitter access to an electromagnetic communication system, comprising: transmitting a first data signal repeated multiple times on a frequency in said communication system, said data signal being transmitted with a first predetermined set of delays between each retransmission; receiving said first data signal by a receiving means, said receiving means splitting said received first data signal into multiple copies, said copies delayed using a reverse of said predetermined first set of delays, said delayed copies of said received first data signal combined together; transmitting a second data signal multiple times on said same frequency in said communication system, said second data signal being transmitted with a second predetermined set of delays, wherein said second data signal is different than said first data signal; and receiving said second data signal, by said receiving means, said receiving means splitting said received second data signal into multiple copies, said copies delayed using the reverse of said predetermined second set of delays, said delayed copies of said received second data signal combined together; and wherein said first predetermined set of delays and said second predetermined set of delays are unique to each other, and wherein said first predetermined set of delays and said second predetermined set of delays do not have identical timing intervals between retransmissions that are identical between two delay sets.
