Aiming at the special space in the tunnel, this paper assumes the geometric distribution of scatterers which is totally different from on the ground, puts forward a new GBSB model of MIMO channel and deduces the space-time correlation function of the model. The results of theoretical analysis and simulation show that the model can more accurately reflect the factors which impact the channel correlation...

This paper presents a novel space-time fast frequency hopping (FFH) multiple input multiple output (MIMO) wireless communication system over rayleigh fading channel. With the M-ary frequency shifting keying (MFSK) modulation and noncoherent demodulation, the structure of a new system is discussed based on the combination of FFH technique and MIMO system. The concept of generalized wide-interval FH...
This paper presents a channel estimation scheme that is designed for MIMO-OFDM systems capable of operating in time varying and frequency selective propagation channels. Orthogonality is applied, either in space- frequency, or in space-time dimensions interchangeably for both the preamble and pilot symbols. The efficiency of the system is based on the accuracy of the channel estimation and tracking...
In this paper, a novel multiple-input multiple-output (MIMO) coded space-time (CST) turbo equalization structure is introduced for single carrier broadband signaling. The new technique exploits transmit diversity, path diversity as well as coding gain through turbo iterations over the decoder branches in the receiver, and it is referred to as coded space-time single carrier transmission with soft...
