Patent number: 10153805Abstract: This invention teaches to the details of an interference suppressing receiver for suppressing intra-cell and inter-cell interference in coded, multiple-access, spread spectrum transmissions that propagate through frequency selective communication channels to a multiplicity of receive antennas. The receiver is designed or adapted through the repeated use of symbol-estimate weighting, subtractive suppression with a stabilizing step-size, and mixed-decision symbol estimates. Receiver embodiments may be designed, adapted, and implemented explicitly in software or programmed hardware, or implicitly in standard RAKE-based hardware either within the RAKE (i.e., at the finger level) or outside the RAKE (i.e., at the user or subchannel symbol level). Embodiments may be employed in user equipment on the forward link or in a base station on the reverse link. It may be adapted to general signal processing applications where a signal is to be extracted from interference.Type: GrantFiled: August 22, 2016Date of Patent: December 11, 2018Assignee: III HOLDINGS 1, LLCInventors: Tommy Guess, Michael L. McCloud, Vijay Nagarajan, Gagandeep Singh Lamba

Patent number: 9602158Abstract: A receiver in a CDMA system comprises a front end processor that generates a combined signal per source. A symbol estimator processes the combined signal to produce symbol estimates. An S-Matrix Generation module refines these symbol estimates based on the sub channel symbol estimates. An interference canceller is configured for cancelling interference from at least one of the plurality of received signals for producing at least one interference-cancelled signal.Type: GrantFiled: September 30, 2014Date of Patent: March 21, 2017Assignee: III HOLDINGS 1, LLCInventors: Gagandeep Singh Lamba, Tommy Guess, Michael McCloud, Anand P. Narayan
