Joint transmission (JT)-based Coordinated Multipoint (CoMP) systems achieve high performance gains by allowing full coordination among multiple cells, transforming unwanted intercell interference into useful signal power. In this paper, we present an analytical model to perform adaptive modulation for a typical JT CoMP system, consisting of three transmission points, under a target bit error rate...
A novel Multiple-input Multiple-output (MIMO) detection scheme based on orthogonal experimental design (OED) is proposed in this paper. By exploiting the initial solutions given by linear detection and non-linear detection algorithms, a searching subspace is constructed to obtain additional performance gain. Exhaustive searching method is optimal in the subspace, but with quite high complexity. Then...
It is known that traditional water-filling provides a closed form solution for capacity maximization in frequency-selective block fading channels or multicarrier system with adaptive modulation. This waterfilling solution is derived from a maximum mutual information argument with single transmission point. Motivated by the new technology of coordinated multiple point (CoMP) transmission , a new closed...
Next generation wireless communication systems, such as 3GPP LTE-Advanced and ITU IMT-Advanced, are demanded to support 1Giga-bit per second (Gbps) peak data rate. Compared with traditional systems, 1Gbps high throughput systems have some different difficulties in system design and hardware implementation. This paper mainly presents some important design criterions and novel methods on parameter design...
Adaptive modulation and coding (AMC) scheme suffers performance degradation with the signaling feedback delay, as channel state information (CSI) is outdated with time variant channel. In this paper, we propose a robust AMC scheme to mitigate the effect of signaling feedback delay, especially in vehicular environments. Channel information estimated in current time interval is utilized to obtain the...
