We use iterative detection [6] to further improve the performance of V-BLAST detection and two types of iterative V-BLAST detection are considered. The first (called the hard decision iterative V-BLAST in this paper) uses the hard symbol replica which is obtained from the hard decision result. …

What is the advantage of V-blast?

V- BLAST (Vertical Bell-Labs Layered Space-Time) algorithm is one of them, which uses a layered structure. This algorithm offers exceptionally superior error performance than conventional linear receivers and still has low complexity.

Which architecture arranges the layers diagonally in space and time?

diagonal BLAST
The diagonally-layered space-time architecture proposed by Foschini [1], now known as diagonal BLAST (Bell Laboratories Layered Space- Time) or D-BLAST, is one such approach.

What is V blast algorithm?

V-BLAST (Vertical-Bell Laboratories Layered Space-Time) is a detection algorithm to the receipt of multi-antenna MIMO systems. Available for the first time in 1996 at Bell Laboratories in New Jersey in the United States by Gerard J. Foschini. He proceeded simply to eliminate interference caused successively issuers.

What is V blast system?

V-BLAST (Vertical-Bell Laboratories Layered Space-Time) is a detection algorithm to the receipt of multi-antenna MIMO systems.

Which technology does not use MIMO?

Which of the following technology does not use MIMO? Explanation: MIMO is used in mobile radio telephone standards such as recent 3GPP and 3GPP2. In 3GPP, High-Speed Packet Access plus (HSPA+) and Long Term Evolution (LTE) standards take MIMO into account. Moreover, MIMO is also used in Wifi and WiMax.

What is spatial multiplexing in MIMO?

Spatial multiplexing in wireless communications is based on multi-input and multiple-output (MIMO) technology where multiple antennas at both the transmitter and receiver are used to carry multiple data streams simultaneously within the same frequency band.

What is V blast MIMO?

What is D blast?

D-BLAST is an effective MIMO technique [2] that has been originally developed for a single-carrier system with flat fading channel. In this paper, we will use this technique for a MIMO-OFDM system, which can be shown in Figure 1.

What is 2×2 MIMO technology?

MIMO or Multiple-Input Multiple-Output (MIMO) is a wireless technology that uses multiple transmitters and receivers to transfer more data at the same time. This is commonly coined as 2×2 MIMO which refers to a configuration with two transmitter antennas and two receiver antennas.
