The throughput of a wireless network is often limited by interference caused by multiple concurrently active nodes. The conventional approach of using a “one-transmission-ata-time” MAC protocol to combat interference leads to a significant loss of achievable throughput compared to schemes such as interference cancellation that keep all transmitters active simultaneously. Unfortunately, interfer...

| Space-time coding and interference cancellation based on orthogonal projection are powerful techniques to improve the communication quality and capacity in downlink CDMA systems. Space-time encoder output stream is transmitted through fading channel using multiple transmitter antennas, increasing communication reliability against multipath fading. On the other hand, orthogonal projection-base...

The wide-band code division multiple access (WCDMA) based third generation wireless communication systems are designed to meet the increasing demands for high data rate applications and greater mobility. High data rate applications include voice, video telephony, Video streaming, File Transfer protocol (FTP), high quality image and wireless full internet access. WCDMA systems are expected to of...

We develop adaptive self-interference cancellation algorithms for both filter-and-forward and decode-and-forward multiple-input multiple-output relays. The algorithms are blind in the sense that they only exploit the spectral properties of the transmitted signal to identify the self-interference channel, while dealing with frequency-selective channels and arbitrary signal spectra. Our approach ...

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...

In the first part, an iterative receiver for joint channel estimation and cochannel interference cancellation suitable for time-division multiple-access (TDMA) cellular radio systems is proposed. The receiver is based on joint maximum-likelihood sequence estimation (JMLSE). It is blind with respect to the data of the interfering users but training-based with respect to the data of the desired u...

In this chapter, we propose a new scheme for Multi User Detection (MUD) using Parallel Interference Cancellation (PIC) technique. This technique provides a good complexity, latency, and performance compromise. Among spread-spectrum techniques, the most popular one is the Direct-Sequence Code-Division Multiple-Access (DS-CDMA), where each active user’s data is modulated (multiplied) by a unique ...

Multi input multi output system (MIMO) has become a viable option to meet the demand of high data rate wireless communication. But MIMO system performance is severely affected by the presence of co-channel interference (CCI). CCI cancellation in MIMO channel therefore is a challenging area of research. This paper provides a Kalman Filter based CCI cancellation approach which is connected to pha...
