Training design for precoded BICM-MIMO systems in block-fading channels
In order to improve bandwidth efficiency and error performance, a new training scheme is proposed for bitinterleaved-coded modulation in multiple-input multiple-output (BICM-MIMO) systems. Typically, in a block-fading channel, the training overhead used for obtaining channel knowledge is proportional to a power of 2 of the number of transmit antennas. However, this overhead can be reduced by em...
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 کاملPrecoder Design for BICM-MIMO Systems Under Channel Estimation Error
If properly designed, the use of a linear precoder can achieve the maximum coding gain and diversity order in bit-interleaved coded modulation with multiple-input multipleoutput systems. However, such maximum coding gain and diversity order are compromised under the practical scenario of having imperfect channel state information (CSI) at the receiver. To alleviate the impact of imperfect CSI o...
متن کاملRobust Codes for 2× 2 MIMO Block Fading Channels
Golden space-time trellis coded modulation (GSTTCM) scheme was proposed in [1] for a high rate 2×2 multipleinput multiple-output (MIMO) system over slow fading channels. In this paper, we present the design criteria of GST-TCM over general block fading channels, where the channel matrix is constant over a fraction of the codeword length and varies from one fraction to another independently. How...
متن کاملJoint Source-Channel Codes for MIMO Block Fading Channels
We consider transmission of a continuous amplitude i.i.d source over an L-block Rayleigh fading Mt × Mr MIMO channel when the transmitter has no channel state information. Due to strict delay requirements Shannon’s source-channel separation theorem becomes obsolete and the optimal performance requires a joint optimization of the source and channel variables. Our goal is to minimize the expected...
