چکیده
Emerging digital radar concepts such as orthogonal frequency-division multiplexing (OFDM) allow flexible signal generation. This opens up new opportunities in waveform design a multiple-input multiple-output (MIMO) system introducing coding for multiplexing. In this article, coded MIMO OFDM waveforms are proposed and investigated that continuous simultaneous wideband transmission all transmitters of multiple transmit receive antenna array spatial environment perception. Challenges operation derived, three strategies introduced analyzed. Their potential is validated compared to the standard subcarrier interleaving approach using simulations measurements an experimental 4 × $ 4$ at 77GHz.

Turbo coded MIMO-OFDM systems
Increasing demand for high-performance 4G broadband wireless is done by the use of multiple antennas at both sides transmitting and receiving. Multiple antenna technologies allow high capacities suited for Internet and multimedia services, and also increase range and reliability of communication systems. Orthogonal frequency-division multiplexing (OFDM) is a popular method for high-data-rate wi...
متن کاملPer-antenna-coded schemes for MIMO OFDM
Two Per-Antenna-Coding (PAC) receiver schemes for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) are described and compared in this paper. In MIMO, the data to transmit are multiplexed onto different antennas. With PAC (sometimes called horizontal coding), these different data streams are encoded separately. For the receiver, two schemes are proposed to ...
متن کاملICI Reduction Through Shaped OFDM in Coded MIMO-OFDM Systems
The default pulse shaping filter in the conventional multiple-input and multiple-output (MIMO) based orthogonal frequency division multiplexing (OFDM) system is a rectangular function, which unfortunately is highly sensitive to frequency synchronization errors and the Doppler spread. Shaped OFDM is able to considerably alleviate the effect of inter-carrier interference (ICI) as well as reduce t...
متن کاملMIMO Radar Ambiguity Optimization using Phase Coded Pulse Waveforms
Multiple input multiple output radars transmit partially coherent or noncoherent waveforms for improving spatial resolution or spatial diversity. While waveform design for SIMO radars concentrate on improving the delay and Doppler resolution characteristics, waveform design for MIMO radars involve optimization of delay, Doppler and spatial resolution characteristics. The resolution properties o...

This paper proposes an adaptive joint combination of the maximum likelihood detection (MLD) and MMSE detection with successive interference cancellation (MMSE-SIC) for MIMO-OFDM coded system. The coded system employs the linear convolutional code as the channel encoder, in order to deal with the severe fading. The cyclic redundancy check (CRC) is attached in the tail of the channel coder to det...
