Efficient Multiuser Detection for High-Capacity Cellular Downlink

A system and method for decoding an intended transmission includes a user device that receives a downlink transmission containing a user signal intended for the user device and one or more interfering user signals directed to one or more other user devices. The user device obtains power stacking information that includes a power level for each of the user signals contained in the received downlink transmission. A channel is estimated using pilot signals in the downlink transmission. Each interfering user signal contained in the downlink transmission is demodulated and decoded using the power stacking information. The user device removes all interfering user signals from the received downlink transmission to obtain the user signal intended for the user device.
