Gregory Edward Bottomley, Paul Wilkinson Dent, Ali S Khayrallah, Huseyin Arslan: Baseband processors and methods and systems for decoding a received signal having a transmitter or channel induced coupling between bits. Ericsson, Myers Bigel Sibley & Sajovec, February 24, 2004: US06697441 (87 worldwide citation)

Received signals are decoded based on a coupling between bits of the received signals introduced by the channel over which the signal is transmitted or by the transmitter which transmitted the signals. For example, in a higher-order modulation scheme, such as 8-PSK, individual bits grouped in a give ...

Mustafa E Sahin, Ismail Guvenc, Huseyin Arslan: Method for iterative interference cancellation for co-channel multi-carrier and narrowband systems. NTT Docomo, Haynes and Boone, April 10, 2012: US08155595 (22 worldwide citation)

In a co-channel deployment of narrowband and multi-carrier technologies (e.g., a femtocell and a macrocell), a method provides cancelling of interference which treats the co-channel signals as desired signals and enhances each of them iteratively. At each iteration, each signal is demodulated and re ...
