The development of low complexity, high performance spatial-multiplexing MIMO detectors continues to be an important area of research capable of increasing the spectral efficiency and capacity of wireless networks. The Markov Chain Monte Carlo (MCMC) detector has shown promise as a high performance method with low complexity growth. We present a solution to the high SNR stalling problems of previous...
This paper examines the application of a packet format that we introduce for Doppler scaling estimation in multicarrier signals. Both orthogonal frequency division multiplexing (OFDM) and filterbank multicarrier (FBMC) signals are examined in an at-sea experiment. We also investigate the use of non-uniform fast Fourier transform (NUFFT) for compensation of Doppler scaling effects. The proposed packet...
This paper introduces the use of non-uniform fast Fourier transform (NUFFT) in detection of orthogonal frequency division multiplexing (OFDM) in a situation when the received signal samples are unevenly spaced. The application of interest to us is underwater acoustic communications, where the relatively low speed of (acoustic) signal propagation in water combined with movement of communicating vehicles...
The third generation partnership project (3GPP) long term evolution (LTE) radio standard has adopted a special form of orthogonal frequency division multiplexing (OFDM) method for the uplink of multiple access networks. This method which is called single carrier frequency division multiple access (SC-FDMA) applies a precoding to each user data set in each OFDM symbol to control its peak-to-average...
