Abstract :
This letter discusses the decoding of a block-coded scheme proposed for orthogonal frequency division multiplexing peak power reduction, employing the ordered statistic decoding algorithm. Performance is evaluated by computer simulations over an additive white Gaussian noise channel and compared with the union bound. It is shown that with respect to optimum decoding, significant computational reduction can be achieved without noticeable error performance degradation.
