Various aspects described herein relate to cancelling interference in wireless communications. Energy level detection of a received signal can be performed to determine an allocation size and position corresponding to an interfering device in the received signal. An interference demodulation reference signal (DM-RS) and cyclic shift of the interfering device in the received signal can be determined. It can be determined whether to apply successive interference cancellation on the received signal, based at least in part on the allocation size and position and the DM-RS and cyclic shift, to cancel interference from the interfering device.

Techniques for detecting and cancelling interference in wireless communications

A method for soft remodulation in a receiver of transmissions over a wireless telecommunication system, the method including obtaining from a FEC decoder a-posteriori LLR values, converting the a-posteriori LLR values into bit probabilities and computing improved soft symbols estimates as expected values using the bit probabilities in a recursive algorithm. Preferably, the step of converting is implemented using a pre-computed Look Up Table (LUT). Preferably, the step of computing is implemented in a Multiplier-Accumulator having a SIMD structure.

Method for soft modulation in a wireless telecommunication network

A method and system for processing LLRs, in a receiver, of transmissions over a wireless telecommunication system, the method including receiving multiple soft symbols, selecting a set of appropriate instructions for LLR calculation for the soft symbols, arranging the soft symbols in a register of a processor according to the selected instructions, selecting an appropriate single instruction from the set of instructions to be implemented by the processor using the soft symbols in the register as operands, and calculating, by a computation unit, multiple LLR values for the multiple soft symbols, in parallel, by means of the selected instruction.
