Patent ID: 8811545

Claim:
A method for reducing interference in a received orthogonal frequency division multiplexing (OFDM) symbol modulated according to selected constellation points s k , wherein the received symbol includes a set of pilot signals and a set of data signals y k , and k is a number of consecutive subcarriers used for the pilot and the data signals, comprising steps of: thresholding the set of pilot signals to detect interfering pilot signals; erasing the detected interfering pilot signals; estimating channels Ĥ k using remaining pilot signals; Ĥ k determining, for each bit b i , in the set of data signals, a logarithmic likely ratio (LLR) log ⁢ ∑ s k : b i = 0 ⁢ 1  y k - H ^ k ⁢ s k  2 ∑ s k : b i = 1 ⁢ 1  y k - H ^ k ⁢ s k  2 ; and decoding the set of data signals based on the determined LLR, wherein the steps are performed in a receiver, wherein k and i are integers.
