— This paper proposes and analyzes receiver schemes for multiple-input multiple-output (MIMO) systems with hybrid automatic-repeat-request (HARQ). It is shown by means of analysis as well as computer simulations that the proposed receiver schemes have optimal decoding performance in the sense that all the relevant information is fully used.

— This paper presents an exact analysis of the effect of the carrier frequency offset on orthogonal frequency division multiplexing (OFDM) systems for a general multipath fading channel. As is well known, the carrier frequency offset attenuates the desired signal and causes inter-carrier interference, thus reducing the signal-to-noise ratio (SNR). The SNR(More)
— This letter analyzes the effect of the carrier frequency offset on orthogonal frequency division multiplexing (OFDM) systems for multipath fading channels. A simple approximate expression for the average signal-to-noise ratio (SNR) is derived. This approximate expression is shown to be an upper bound of the average SNR for flat fading channels and an(More)
Breast cancer metastasis suppressor 1 (BRMS1) was originally identified as an active metastasis suppressor in human breast cancer. Loss of BRMS1 expression correlates with tumor progression, and BRMS1 suppresses several steps required for tumor metastasis. However, the role of BRMS1 in hepatocellular carcinoma (HCC) remains elusive. In this study, we found(More)
— This paper analyzes the effect of the carrier frequency offset on frequency-domain differential demodulation in orthogonal frequency division multiplexing (OFDM) systems. The exact signal-to-noise ratio (SNR) expression is derived in the presence of the frequency offset. Using this exact SNR expression, the SNR degradation due to the frequency offset is(More)
— This paper presents a blind frequency offset estimation algorithm for OFDM systems. The blind algorithm is compared to two popular frequency offset estimation algorithms. The first is the cyclic prefix-based (CPB) algorithm, which is blind but does not perform well in frequency selective channels. The second is the the pilot tone-aided (PTA) algorithm,(More)
