چکیده

The iterative receivers with LSD and PIC on slow Rayleigh fading MIMO channels are considered. The convergence behavior of the iterative detection and decoding is analyzed via VTR. We present an iterative receiver with detection switching and show that this scheme is able to considerably reduce the complexity of receiver without performance degradation.

Improved Max-Log-MAP BICM-IDD receiver for MIMO systems

A novel bit-interleaved coded modulation with iterative detection and decoding (BICM-IDD) receiver for multiple-input and multipleoutput (MIMO) systems using Max-Log-MAP algorithm is proposed. This receiver improves the detection and decoding performance by an improved turbo principle, in which pre-scaling the input information of the detector is performed at each iteration. From an information...

Analysing bit-interleaved coded modulation in multiple-input multiple-output systems with channel estimation error

The performance of bit-interleaved coded modulation in multiple-input multiple-output (BICM-MIMO) systems using an iterative channel estimator is analysed. In a conventional iterative channel estimator, after initialisation with the training phase, the channel estimator switches to the data phase. However, such a conventional iterative channel estimator does not always improve the performance o...

Soft-input iterative channel estimation for bit-interleaved turbo-coded MIMO-OFDM systems

Bit-interleaved coded modulation (BICM) is a robust multiplexing technique for achieving multiplexing gain in multiple-input multiple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) systems. However, in order to benefit maximally from the various advantages offered by BICM-based MIMO-OFDM systems, availability of accurate MIMO channel state information (CSI) at the receiver end ...

Semi-blind Channel Estimation and Iterative Detection for MIMO-OFDM Systems

The combination of MIMO and OFDM techniques has been recently explored for providing high speed data communication over fading dispersive channels. Bit interleaved coded modulation (BICM) architecture with iterative detection and decoding techniques (IDD) at the receiver has been found to attain good performance (close to Turbo MIMO) with moderate complexity. The scheme however relies on the av...
