title = "An MMSE beamforming algorithm based hybrid carrier system over doubly selective channels",
abstract = "In this paper, we proposed an MMSE Beamforming algorithm based hybrid carrier (HC) system over doubly selective channels. HC system based on 4-weighted fractional fourier transform (4-WFRFT) has been proved to be a better choice over doubly selective channels. By exploiting 4-WFRFT, the modulation mode of the system can be switched between single carrier (SC) system and orthogonal frequency division multiplexing (OFDM) system and can be matched with the characteristics of doubly selective channels. This paper presents an adaptive MMSE beamforming algorithm for HC system with a linear array antenna. The optimal weight vector of the algorithm is derived by pilot signals. In case of knowing the exact direction of arrival (DOA), HC system with MMSE beamforming algorithm can achieve a great improvement of BER performance, in comparison to that without MMSE beamforming algorithm. Moreover, HC system, under proper modulation order, performs better than SC and OFDM system with MMSE beamforming algorithm over the typically doubly selective channels.",
