Low Complexity Interference Cancellation Method for mMTC Devices

Low complexity MMSE interference cancellation for LTE uplink MIMO receiver

In this paper, we propose a novel low complexity minimum mean square error (MMSE) interference cancellation (IC) to minimize the residual inter-symbol and inter-antenna interference in LTE/LTE-Advanced uplink. In the LTE/LTEAdvanced base station, frequency domain equalizers (FDEs) are adopted to achieve good performance. However, in multi-tap channels, the residual interference of FDE still deg...

Low complexity successive interference cancellation for MIMO-OFDM systems

Layered architectures like theV-BLAST scheme are a promising candidate to exploit the capacity advantages of multiple antenna systems leading to practical wireless communication schemes with very high data rates. The combination with orthogonal frequency division multiplexing (OFDM), called MIMO–OFDM, with per-antenna-coding is one of the most likely implementations of these multilayer architec...

LTE uplink MIMO receiver with low complexity interference cancellation

In LTE/LTE-A uplink receiver, frequency domain equalizers (FDE) are adopted to achieve good performance. However, in multi-tap channels, the residual inter-symbol and inter-antenna interference still exist after FDE and degrade the performance. Conventional interference cancellation schemes can minimize this interference by using frequency domain interference cancellation. However, those scheme...

Beyond digital interference cancellation Joint RF-baseband interference cancellation to reduce receiver complexity and power consumption

Joint RF-baseband interference cancellation to reduce receiver complexity and power consumption. Summary One of the major drawbacks towards the realization of MIMO and multi-sensor wireless communication systems is that multiple antennas at the receiver each have their own separate radio frequency (RF) front ends and analog to digital converter (ADC) units, leading to increased circuit size and...
