Joint Spatial and Temporal PAR Reduction in MIMO OFDM
Multicarrier systems suffer from the high peak-to-average power ratio (PAR) of their transmit signal. In order to overcome this issue, peak-power reduction schemes have been developed. One of the most popular technique is selected mapping (SLM). Recently, a variant of SLM for single-antenna systems was proposed. This scheme considers temporally consecutive OFDM frames to achieve a further gain ...
متن کاملJoint BLAST-STTC for MIMO-OFDM System
— This study focuses on improving MIMO-OFDM systems by combining a wireless communication architecture known as vertical BLAST(bell laboratories layered space-time) or V-BLAST and STTC(space time trellis coding). In this paper, the combination is done by introducing STTC in each V-BLAST layer. Moreover, this architecture uses multiple antennas that are grouped into small number of antennas whic...
متن کاملJoint Estimation of Impairments for OFDM and MIMO OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) is a multi–channel modulation technique that makes use of Frequency division multiplexing (FDM) being modulated by a low bit rate digital stream. The main reason of using OFDM is because here the symbol detection is easy and also to increase the robustness against frequency selective fading and narrow band interference. Certain parameter like CF...
متن کاملPerformance Analysis of MIMO-OFDM by Spatial
The main aim of OFDM-MIMO systems is to combine OFDM technology with the techniques of MIMO systems. The growing demand of multimedia services and the growth of Internet related contents lead to increasing interest to high speed communications. OFDM is a type of multichannel modulation that divides a given channel into many parallel sub channels or subcarriers, so that multiple symbols are sent...
متن کاملAnalog Joint Source-Channel Coding for MIMO-OFDM Systems
Analog Joint Source-Channel Coding (JSCC) has been shown to approach the optimal distortion-cost tradeoff when transmitting over AWGN channels. In this work we consider analog JSCC over frequency-selective channels using Orthogonal Frequency Division Multiplexing (OFDM) modulation and multiple antennas at transmission and/or reception, i.e. using a MIMO-OFDM system. Due to its high complexity, ...
