In this paper, an effective preamble structure with only one zero-value guard symbols for OFDM/OQAM systems is proposed to improve spectrum efficiency. Moreover,a preamble interference cancellation (PIC) based channel estimation (CE) scheme is proposed to mitigate the residual ISI in OFDM/OQAM systems. Simulation results prove that the proposed(More)
Orthogonal frequency division multiplex/offset QAM (OFDM/OQAM) has been proven to be a promising multi-carrier modulation (MCM) technique for the transmission of signals over multipath fading channels. However, OFDM/OQAM has also the intrinsic disadvantage of high peak-to-average-power ratio (PAPR) that should be alleviated. In this paper, a novel selective(More)
In this paper, a simple transmit diversity scheme using two transmitting and two receiving antennas for STBC structure is presented. Moreover, a detection algorithm with iterative interference cancellation for STBC-OFDM/OQAM system is proposed to improve bit error ratio performance. Simulation results prove that the proposed detection algorithm is an(More)

Orthogonal frequency division multiplexing offset-QAM (OFDM/OQAM) is a promising multicarrier transmission technique for its merits such as operating without cyclic prefix (CP) and flexibility of introducing well time-frequency localized pulse shapes. However, under dispersive channel condition, the intrinsic inter-symbol and inter-carrier interference(More)
OBJECTIVE To compare cardiac adverse events, clinical outcomes and mid-and-long-term effects among massive and sub-massive pulmonary embolism (PE) patients under different periodswho received thrombus fragmentation by pigtail catheter. METHODS Two groups of patients who receivedthrombusfragmentation bypigtail catheter in different periods were analyzed(More)
In this paper, we compare the performance between channel estimation based on compressed sensing (CS) and time-domain least square (LS) for single-carrier (SC) communication system. Unlike the conventional channel estimation techniques such as frequency domain LS which is used in the condition that the length of pilot sequence is equal to data sequence, the(More)
