Coherent Joint Transmission in Downlink Heterogeneous Cellular Networks

The analysis of the success probability or signal-tointerference ratio (SIR) distribution for coherent joint transmission (JT) based on stochastic geometry is an open issue. In this letter, we study coherent JT in downlink heterogeneous cellular networks and provide an upper bound of the success probability for the general user and the worst-case user (cell-corner user), and an approximation fo...

Heterogeneous Downlink Cellular Networks

We characterize the ergodic spectral efficiency of a non-cooperative and a cooperative type of K-tier heterogeneous networks with limited feedback. In the non-cooperative case, a multi-antenna base station (BS) serves a single-antenna user using maximum-ratio transmission based on limited feedback. In the cooperative case, a BS coordination set is formed by using dynamic clustering across the t...

Analysis of Joint Transmit-Receive Diversity in Downlink MIMO Heterogeneous Cellular Networks

We study multiple-input multiple-output (MIMO) based downlink heterogeneous cellular network (HetNets) with joint transmit-receive diversity using orthogonal space-time block codes at the base stations (BSs) and maximal-ratio combining (MRC) at the users. MIMO diversity with MRC is especially appealing in cellular networks due to the relatively low hardware complexity at both the BS and user de...

Robust optimization for multi-antenna downlink transmission in cellular networks

In multi-cell networks where resources are aggressively reused and the cell sizes are shrinking to accommodate more users, eliminating interference is the key factor to reduce the system energy consumption. This growth in the demand of wireless services has urged the researchers to find new and efficient ways of increasing coverage and reliability, i.e., coordinated signal processing across bas...

Cooperative Transmission for the Downlink of Multiuser Mimo Cellular Networks

COOPERATIVE TRANSMISSION FOR THE DOWNLINK OF MULTIUSER MIMO CELLULAR NETWORKS Yakup Kadri Yazarel M.S. in Electrical and Electronics Engineering Supervisor: Asst. Prof. Dr. Defne Aktaş August, 2007 In this thesis, we propose a distributed transmission scheme for the downlink of a multiuser system. The base-stations (BSs) cooperate with each other with limited, local message-passing to find the ...
