Effects of clipping and filtering on the performance of OFDM
Xiaodong Li,Leonard J. Cimini +1 more
TL;DR: This work investigates, through extensive computer simulations, the effects of clipping and filtering on the performance of OFDM, including the power spectral density, the crest factor, and the bit-error rate.
Journal ArticleDOI
Bit-interleaved coded modulation with iterative decoding
Xiaodong Li,James A. Ritcey +1 more
TL;DR: A simple iterative decoding technique using hard-decision feedback is presented for bit-interleaved coded modulation (BICM), making BICM with iterative decode suitable for both types of channels.
Journal ArticleDOI
Bit-interleaved coded modulation with iterative decoding and 8 PSK signaling
TL;DR: It is shown that at high signal to noise ratios, the performance of BICM-ID converges to the performance assuming error-free feedback, and the analytical bounds on the performance with an ideal feedback assumption are provided.
Proceedings ArticleDOI
Effects of clipping and filtering on the performance of OFDM
Xiaodong Li,Leonard J. Cimini +1 more
TL;DR: This work investigates, through extensive computer simulations, the effects of clipping and filtering on the performance of OFDM, including the power spectral density, the bit error rate, and the PMEPR, and shows that clip and filtering is a promising technique for the transmission of OfDM signals using realistic linear amplifiers.
Journal ArticleDOI
Trellis-coded modulation with bit interleaving and iterative decoding
Xiaodong Li,James A. Ritcey +1 more
TL;DR: It is shown that convolutional codes with good Hamming-distance property can provide both high diversity order and large free Euclidean distance for BICM-ID, which provides a simple mechanism for variable-rate transmission.
