A receiver in a communication system is provided that includes a synchronization module and a channel estimator. The synchronization module is configured to identify an end of a cyclic prefix (CP) in a received signal using slope detection by monitoring a detection metric threshold in the received signal. The channel estimator is configured to estimate a complex noise variance using guard band subcarriers.

A LDPC decoder utilizes a new schedule that breaks a dependency between data of different layers of a parity check matrix, so that the forward scan in the next layer can begin to perform after a predetermined time has elapsed (i.e. a delay) since the backwards scan of the previous layer has begun, and before the backwards scan of the previous layer is completed. Accordingly, the computation at the next layer can begin as soon as possible.

An apparatus relating generally to matrix inversion is disclosed. This apparatus includes a matrix inversion module coupled to receive matrix information and to provide an approximation of an inversion of the matrix information. The matrix inversion module comprises a decomposition block coupled to receive the matrix information and to decompose the matrix information into diagonal matrix information and off diagonal matrix information, and an expansion block. The expansion block is coupled to receive the diagonal matrix information and the off diagonal matrix information, and to invert a matrix sum of the diagonal matrix information and the off diagonal matrix information by generation of a portion of a series expansion.

A wireless receiver is constructed to equalize a time-domain received signal, detect a plurality of symbols of the equalized time-domain received signal, and perform interference cancellation on the time-domain received signal. The interference cancellation can be performed using a partial result produced by an IDFT, and may use only neighboring symbols in a detected plurality of symbols. The resulting wireless receiver can be constructed to operate efficiently under a plurality of wireless standards.
