Patent ID: 8737451

Claim:
A method of mitigating inter-sector interference, the method comprising: performing a pilot interference cancellation technique on pilot sequences in a received signal; and performing a selective interference cancellation technique on the received signal after performing the pilot interference cancellation technique, wherein performing the selecting interference cancellation technique comprises: populating N d columns of an N-column system matrix, the N d columns corresponding to desired data for a first user device, wherein N and N d are integers and N is greater than N d ; evaluating energy in Walsh bins for each sector from which the received signal is received to select N-N d user devices other than the first user device having strongest channel energies; populating a remaining N-N d columns of the system matrix, the remaining N-N d columns corresponding to the selected N-N d user devices; and canceling a subset of code sequences in the received signal related to the remaining N-N d columns of the system matrix.
