MIMO Z Channel Interference Management
نویسنده
چکیده
MIMO Z Channel is investigated in this paper. We focus on how to tackle the interference when different users try to send their codewords to their corresponding receivers while only one user will cause interference to the other. We assume there are two transmitters and two receivers each with two antennas. We propose a strategy to remove the interference while allowing different users transmit at the same time. Our strategy is low-complexity while the performance is good. Mathematical analysis is provided and simulations are given based on our system.

Gaussian Z Channel with Intersymbol Interference
In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...
متن کاملAdaptive limited feedback for interference alignment in MIMO interference channels
It is very important that the radar sensor network has autonomous capabilities such as self-managing, etc. Quite often, MIMO interference channels are applied to radar sensor networks, and for self-managing purpose, interference management in MIMO interference channels is critical. Interference alignment (IA) has the potential to dramatically improve system throughput by effectively mitigating ...
متن کاملMeasured Capacities at 5.8 GHz of Indoor MIMO Systems with MIMO Interference
The capacity performances of two interfering flatfading MIMO links are determined based on measured channels. Time-multiplexing of the links (TDMA), that is, when the MIMO links take turns operating without interference, serves as our baseline case. To this, we compare the spatial-multiplexed case (SDMA), which allows both MIMO links to operate simultaneously. Under SDMA, both open-loop (no cha...
متن کاملModulation-mode and Power Assignment in SVD-assisted Broadband MIMO Systems
Singular-value decomposition (SVD)-based multiple-input multiple-output (MIMO) systems have attracted a lot of attention in the wireless community. However, applying SVD to frequency-selective MIMO channels results in unequally weighted single-input single-output (SISO) channels requiring complex resource allocation techniques for optimizing the channel performance. Therefore, a different appro...
متن کاملCombined Beamforming with Alamouti Coding Using Double Antenna Array Groups for Multiuser Interference Cancellation
This paper propose a new multiple-input multipleoutput (MIMO) signal processing scheme that combines optimum transmit and receive beamforming with the Alamouti space-time block code (STBC) transmission and modifies the decoding process. The scheme uses double antenna array groups to achieve stable performance regardless of direction of arrived (DOA) and angular spread (AS). In a multiuser MIMO ...
