Transmit Diversity v. Spatial Multiplexing in Modern MIMO Systems
A contemporary perspective on the tradeoff between transmit antenna diversity and spatial multiplexing is provided. It is argued that, in the context of most modern wireless systems and for the operating points of interest, transmission techniques that utilize all available spatial degrees of freedom for multiplexing outperform techniques that explicitly sacrifice spatial multiplexing for diver...
متن کاملAdaptive Transmit Diversity and Spatial Multiplexing for MIMO-OFDM Systems
Space-time block coding (STBC) and Spatial multiplexing (SM) or BLAST (Bell Labs Layered Space-Time) are promise approaches that exploit the MIMO channel to provide higher data rates and diversity gains with no sacrifice in bandwidth. In this work, we present a hybrid MIMO scheme that combines transmit diversity and spatial multiplexing. The proposed scheme can achieve arbitrary number of multi...
متن کاملPerformance of MIMO Systems with a Hybrid of Transmit Diversity and Spatial Multiplexing
Spatial multiplexing or BLAST (Bell Labs Layered Space-Time) and space-time block-coding (STBC) are promise approaches that exploits the MIMO channel to provide higher data rates and diversity gains with no sacrifice in bandwidth. In this work we evaluate the performance of a MIMO system that combines transmit diversity and spatial multiplexing schemes. We also propose two effective receiver st...
متن کاملOptimal Diversity Vs Multiplexing Trad Mimo Channe
In this paper we derive the optimal diversity versus multiplexing tradeoff for a frequency selective i.i.d. Rayleigh MIMO channel. This tradeoff is shown to be better than the one of the frequency flat MIMO channel. Traditional approaches for frequency selective channels use OFDM techniques in order to exploit the diversity gain due to frequency selectivity. We show that although coding in OFDM...
متن کاملPerformance Analysis of Transmit Diversity and Spatial Multiplexing MIMO modes Vs. SISO System in LTE-Downlink System
In this paper we evaluate the performance of LTE-Downlink System with different Transmit diversity and Spatial multiplexing MIMO modes in LTE-downlink. Here we analysis performance on BLER-Block Error Rate and Data Throughput vs SNR-Signal to Noise Ratio. Two Transmit Diversity schemes Space Frequency Block Codes (SFBC) and Frequency Switched Transmit Diversity (FSTD) and two Spatial Multiplexi...
