A new DSTM scheme based on Weyl group for MIMO systems with 2, 4 and 8 transmit antennas
نویسندگان
چکیده
In this paper, we propose a differential space-time modulation (DSTM) scheme for multiple input multiple output (MIMO) systems with 2, 4, and 8 transmit antennas. This scheme is used for MIMO systems where the channel coefficients are not available at both the transmitter and the receiver. For 2 transmit antennas, the transmission matrices are selected from Weyl group. We use the Kronecker product of matrices of the Weyl group to design new groups for the schemes using 4 and 8 transmit antennas. Simulation results show the performance of these schemes. Keywords—MIMO, Differential Space-Time Modulation, Noncoherent, Weyl group, Kronecker product.

Unitary Differential Space-Time Modulation with Joint Modulation
We develop two new designs of unitary differential space-time modulation (DSTM) with low decoding complexity. Their decoder can be separated into a few parallel decoders, each of which has a decoding search space of less than N if the DSTM codebook contains N codewords. Both designs are based on the concept of joint modulation, which means that several information symbols are jointly modulated,...

متن کاملTransmission Control Scheme for Throughput Maximization in Mimo Systems
We introduce our throughput maximization transmission control scheme for multiple input multiple output (MIMO) systems [1][2]. The proposed scheme selects a transmission scheme (a set of transmit antennas, modulation, and coding rate) to maximize throughput based on received signal-to-interference-plus-noise ratio (SINR). The proposed scheme achieves high throughtput under any channel condition...
متن کاملX-Network with three antennas
Interference alignment is known to achieve the maximum sum DoF of 4M 3 in the 2 × 2 X-Network (i.e., twotransmitter (Tx) two-receiver (Rx) X-Network) with M antennas at each node, as demonstrated by Jafar and Shamai. Recently, an Alamouti code based transmission scheme, which we call the Li-Jafarkhani-Jafar (LJJ) scheme, was proposed for the 2×2 XNetwork with two antennas at each node. This sch...
