Embodiments of an OFDM receiver and methods for decoding OFDM symbols of two or more data streams with reduced multiplication operations are generally described herein. Other embodiments may be described and claimed. In some embodiments, one or more terms of a modified L-squared-norm cost function are precomputed and stored for predetermined complex symbol values of one or more tones of OFDM symbols prior to performing a searching process. During the searching process, the cost function is computed using the precomputed terms and received data symbols using shifting and adding operations, rather than multiplication operations. In other embodiments, non-L-squared-norm cost functions are used.

OFDM receiver and method for decoding OFDM symbols of two or more data streams with reduced multiplication operations

Embodiments of a multicarrier receiver and method for generating soft bits in a multiple-input multiple-output system are generally described herein. In some embodiments, operational parameters for an equalizer and a soft-bit demapper in a multicarrier receiver are determined. Other embodiments may be described and claimed.

Multicarrier receiver for multiple-input multiple-output wireless communication systems and method

The effects of interference are mitigated in a wireless system by estimating spatial characteristics of an interfering signal, and using those characteristics in the formation of a spatial equalizer.

Interference rejection in wireless networks

In one embodiment, an apparatus includes a correlator unit that generates a set of correlator outputs and a codeword selector coupled to the set of correlator outputs to determine a received codeword therefrom. The correlator unit may have reference signals pre-compensated with intra-codeword interference.
