A system and a method are disclosed and include generating a first kernel based on a tap of a first transmission and a plurality of taps of a second transmission; calculating a first weighted coefficient set based on the first kernel; calculating a first self-interference transmission signal estimation based on the first weighted coefficient set; and obtaining a first cancellation signal by subtracting the first self-interference transmission signal estimation from a downlink received signal.

Method and apparatus for parallel self-interference estimation and cancellation in multiple transmitters carrier aggregation systems

A system and a method are disclosed for normalizing Log-Likelihood Ratios for bits of a transport block. For a narrowband channel estimation (NBCE), a normalization factor is selected based on an estimated delay spread, a cyclic prefix, an estimated Doppler spread, a rank, a modulation and coding scheme (MCS) and a signal-to-noise ratio (SNR) for the transport block, and an input LLRfor the individual bits of the transport block are scaled to respectively form an output LLRfor the individual bits of the transport block using the normalization factor. For a wideband channel estimation, a normalization factor is selected based on the rank/MCS/SNR of the transport block, and the input LLRfor the individual bits of the transport block are scaled to respectively form the output LLRfor the individual bits of the transport block using the normalization factor.
