Feedback Quantization for Linear Precoded Spatial Multiplexing
This paper gives an overview and a comparison of recent feedback quantization schemes for linear precoded spatial multiplexing systems. In addition, feedback compression methods are presented that exploit the time correlation of the channel. These methods can be roughly divided into two classes. The first class tries to minimize the data rate on the feedback link while keeping the performance c...
متن کاملAdaptive Feedback Reduction for Precoded Spatial Multiplexing Mimo Systems
In this paper we extend feedback compression schemes for precoded spatial multiplexing multiple-input multiple-output (MIMO) systems to adapt to changing channel characteristics. The presented schemes use the past feedback to estimate the conditional probability of a precoder occurrence given the last feedback at runtime. These probabilities are then used to losslessly compress the feedback.
متن کاملLimited Feedback Precoding for Spatial Multiplexing Systems Using Linear Receivers
Multiple-input multiple-output (MIMO) spatial multiplexing wireless systems achieve high spectral efficiencies by demultiplexing the incoming bit stream into multiple substreams. Spatial multiplexing is of practical importance because the multiple substreams can be decoded using linear receivers. Unfortunately, this reduction in complexity degrades the probability of error performance. To overc...
متن کاملPrecoded Spatial Multiplexing MIMO Systems in Time- Varying Fading Channel
Conventional precoded spatial multiplexing multiple-input multiple-output (MIMO) systems using limited feedback are mainly based on the notion of time invariant channels throughout transmission. Consequ-encely, the precoding matrix can be found during the training symbols and used over the subsequent data symbols. In this paper, a more practical system where the channel varies from one block of...
متن کاملLimited feedback precoding for spatial multiplexing systems
Spatial multiplexing multiple-input multiple-output (MIMO) wireless systems are of both theoretical and practical importance because they can achieve high spectral efficiencies by demultiplexing the incoming bit stream into multiple substreams. It has been shown that sending fewer substreams than the number of transmit antennas by linear precoding can provide improved error rate performance. Me...
