Partial transmit sequence (PTS) scheme is one of the most popular peak-to-average power ratio (PAPR) reduction schemes for orthogonal frequency division multiplexing (OFDM) systems. In term of PAPR performance, the cyclic shift on time-domain PTS is better than conventional PTS (C-PTS), and the receiver can detect the phase rotations without using side(More)
Beam forming has been greatly applied in TD-SCDMA, but in the 3G long-term evolution (LTE), multi-antenna solution aims to use multi-input-multi-output (MIMO). Usually MIMO requires enough large antenna space to ensure uncorrelated multi-channels, whereas beam forming antennas need small antenna space. But this years’ research has shown the(More)
In this paper, the fast-varying channel estimation method based on basis expansion models (BEM) in IEEE 802.16e systems is researched. BEM is one of the promising methods for fast-varying channel modeling, especially for scenarios where there are significant multipath signals caused by strong reflectors as well as fast-varying path delays due to user(More)
Selected mapping (SLM) scheme is one of the most popular peak-to-average power ratio (PAPR) reduction schemes for orthogonal frequency division multiplexing (OFDM) systems. The main drawbacks of the conventional SLM technique are the computational complexity and the need for transmission of several side information bits, for each data block, which results(More)
