A Learning Approach for Optimal Codebook Selection in Spatial Modulation Systems

Vidit Saxena

In spatial modulation (SM) systems that utilize multiple transmit antennas/patterns with a single radio front-end, we propose a learning approach to predict the average symbol error rate (SER) conditioned on the instantaneous channel state. We show that the predicted SER can be used to lower the average SER over Rayleigh fading channels by selecting the optimal codebook in each transmission instance.

Bayesian Learning based Millimeter-Wave Sparse Channel Estimation with Hybrid Antenna Arrays

Markku Juntti

We consider the problem of millimeter-wave (mmWave) channel estimation with a hybrid digital-analog two-stage beamforming structure. A radio frequency (RF) chain excites a dedicated set of antenna subarrays. To compensate for the severe path loss, known training signals are beamformed and swept to scan the angular space. Since the mmWave channels typically exhibit sparsity, the channel response can usually be expressed as a linear combination of a small number of scattering clusters.

CLUSTERING-GUIDED GP-UCB FOR BAYESIAN OPTIMIZATION

Jungtaek Kim

Bayesian optimization is a powerful technique for finding extrema of an objective function, a closed-form expression of which is not given but expensive evaluations at query points are available. Gaussian Process (GP) regression is often used to estimate the objective function and uncertainty estimates that guide GP-Upper Confidence Bound (GP-UCB) to determine where next to sample from the objective function, balancing exploration and exploitation. In general, it requires an auxiliary optimization to tune the hyperparameter in GP-UCB, which is sometimes not easy to carry out in practice.

A FAST BAYESIAN ALGORITHMIC ENHANCEMENT FOR REAL TIME BIT ERROR RATIO TEST (BERT)

JackS Wong

Continuous, real-time bit error ratio (BER) test of modern communication and storage channels is a ubiquitous problem: the noises tend to vary in space and time, and are difficult to fully characterize offline. Traditional method requires time consuming accumulation of samples for which Bayesian method has shown its promise in alleviating by incorporating a priori knowledge. However, the method has so far depended on a simplistic linear search algorithm that suffers from long running time which defeats the purpose of sample reduction.

DIRICHLET PROCESS MIXTURE MODELS FOR CLUSTERING I-VECTOR DATA

Shreyas Seshadri

Non-parametric Bayesian methods have recently gained popularity in several research areas dealing with unsupervised learning. These models are capable of simultaneously learning the cluster models as well as their number based on properties of a dataset. The most commonly applied models are using Dirichlet process priors and Gaussian models, called as Dirichlet process Gaussian mixture models (DPGMMs). Recently, von Mises-Fisher mixture models (VMMs) have also been gaining popularity in modelling high-dimensional unit-normalized features such as text documents and gene expression data.

Robust Estimation of Self-Exciting Point Process Models with Application to Neuronal Modeling

Abbas Kazemipour

We consider the problem of estimating discrete self- exciting point process models from limited binary observations, where the history of the process serves as the covariate. We analyze the performance of two classes of estimators: l1-regularized maximum likelihood and greedy estimation for a discrete version of the Hawkes process and characterize the sampling tradeoffs required for stable recovery in the non-asymptotic regime. Our results extend those of compressed sensing for linear and generalized linear models with i.i.d.
