Patent ID: 8611310

Claim:
An apparatus, comprising: a first device to transmit at a first frequency; a first PN generator to generate a first PN sequence at a first offset, the first PN sequence comprising a first in-phase PN sequence and a first quadrature PN sequence; a first spreader to receive and spread a first pilot data with the first PN sequence; a second device to transmit at a second frequency, the second device co-sited with the first device; a second PN generator to generate a second PN sequence at a second offset, the second PN sequence comprising a second in-phase PN sequence and a second quadrature PN sequence, wherein the first PN sequence is generated from equations different from equations used to generate the second PN sequence, and wherein the first in-phase PN sequence is uncorrelated with the second in-phase PN sequence and the first quadrature PN sequence is uncorrelated with the second quadrature PN sequence; and a second spreader to receive and spread a second pilot data with the second PN sequence in an area co-sited with the spread first pilot data.
