چکیده

In this contribution we present a new family of soft equalizers for multiple input multiple output (MIMO) systems with frequency selective fading. The proposed equalizers are based on soft successive interference cancellation (SIC) of both intersymbol interference (ISI) and multiple antenna interference (MAI), and are applicable to both single user MIMO systems with ISI and MIMO multipath channels with unknown cochannel interference (UCCI). Performance of proposed equalizers is evaluated through Monte Carlo simulations.

Frequency-Domain Iterative SIC for SC-MIMO Multiplexing

Recently, the multi-input multi-output (MIMO) multiplexing technique has been gaining much attention for achieving very high speed data transmissions in a bandlimited wireless channel. However, if single-carrier (SC) transmission is used, the bit error rate (BER) performance significantly degrades due to inter-symbol interference (ISI) resulting from a severe frequencyselective fading channel. ...

Performance of Turbo Interference Cancellation Receivers in Space-Time Block Coded DS-CDMA Systems

We investigate the performance of turbo interference cancellation receivers in the space time block coded (STBC) direct-sequence code division multiple access (DS-CDMA) system. Depending on the concatenation scheme used, we divide these receivers into the partitioned approach (PA) and the iterative approach (IA) receivers. The performance of both the PA and IA receivers is evaluated in Rayleigh...

Iterative FDIC Using 2D-MMSE FDE for Turbo-Coded HARQ in SC-MIMO Multiplexing

Multiple-input multiple-output (MIMO) multiplexing is an attractive technique to achieve very high-speed transmission with a limited bandwidth. Recently, we proposed an iterative frequency-domain interference cancellation (FDIC) for single-carrier MIMO (SC-MIMO) multiplexing. In our previous work, assuming that the interference from the other antennas can be perfectly cancelled in FDIC, one-dim...

Improving MIMO detection by L-value analysis and adaptive threshold-based cancellation

We present an improved algorithm for detection of the received signal of a convolutionally encoded wireless MIMO system. The method is based on BLAST (Bell-Labs Layered Space-Time) algorithm with successive interference cancellation. Compared to existing solutions, cancellation is done adaptively. The receiver uses an MAP soft output demapper combined with an iterative (Turbo-) decoder. Adaptiv...

A Novel Intercarrier Interference Cancellation for MIMO-OFDM Systems

The main impairment of an orthogonal frequency division multiplexing (OFDM) systems is an intercarrier interference (ICI) effect caused by a frequency offset. A zero-padded technique designed for a conjugate cancellation scheme in MIMO-OFDM systems for ICI cancellation is proposed by padding zero between two consecutive symbols over a space-frequency domain. At the receiver, the ICI cancellatio...
