Unitary Precoding Techniques Based on Transmit-MRC for MIMO Wireless Systems
— This paper proposes a low complexity unitary precoding scheme for multiple-input multiple-output (MIMO) systems. The singular-value decomposition (SVD) based transmission is ca...

On the secrecy capacity of frequency-selective fading channels : A practical vandermonde precoding
We study the secrecy capacity of the frequency-selective wiretap channel. Assuming that a guard interval of L symbols is inserted to avoid the inter-block interference and these s...

Throughput Performance of Pre-coding MIMO Transmission with Multi-Beam Selection
Abstract―We have been proposing multi-beam MIMO (MBMIMO) as an Evolved UTRA downlink MIMO scheme for 3GPP long term evolution (LTE). MB-MIMO is a pre-coding MIMO scheme that uses...

Minimum BER beamforming in the RF domain for OFDM transmissions and linear receivers
In this paper, we study transmission schemes for a novel OFDMbased MIMO system which performs adaptive signal combining in radio-frequency (RF). Specifically, we consider the prob...

Bit-Interleaved Coded Multiple Beamforming with Imperfect CSIT
This paper addresses the performance of bit-interleaved coded multiple beamforming (BICMB) [1], [2] with imperfect knowledge of beamforming vectors. Most studies for limited-rate ...
