This paper focuses on soft-output detection when coded spatial data multiplexing schemes are combined with filter bank multicarrier systems based on the offset quadrature amplitude modulation (FBMC/OQAM). Due to the modulationinduced interference, which is inherent to FBMC/OQAM, the soft-output detection is not trivial. The proposed technique circumvents this problem by removing the interferenc...

A multiple-input multiple-output (MIMO) wireless transmission system with continuous phase modulation (CPM) is considered. A novel MIMO CPM receiver with incoherent modulation is presented. The incoherent demodulation of CPM allows an uncomplicated handling of a frequency offset compared to coherent approaches requiring exact knowledge of the carrier frequency. Blind signal separation (BSS) is ...

The cancellation of DC-offsets and 2-order-type RF-self-mixing products (RFS2) is presented for six-port-based, analog direct receiver front-ends. It is shown that the signal dependent RFS2 comprising a dynamic DC-offset as well as the front-end dependent static DC-offset are generated systematically and not only by spurious effects unlike conventional, mixer-based front-ends. Due to this fact,...

A decision feedback circuit with integrated offset compensation is presented in this paper. The circuit is built around the sense amplifier comparator. The feedback loop is closed around the first stage of the comparator resulting in minimum loop latency. The feedback loop is implemented using a switched capacitor network that picks from one of pre-computed voltages to be fed back. The comparat...

Wireless communication technology such as cellular and wireless local area network (WLAN) systems have grown rapidly and generated various competing transmission formats. In the need of seamless communication across incompatible radio standards, software defined radio (SDR) concept has received much attention among researchers working in mobile and personal wireless communications. SDR is a tec...

In minimally invasive hip arthroplasty double offset broach handles are used, to facilitate the preparation of the femoral canal. The aim of this study was to quantify the differences in force and impulse transmission between two double offset broach handles and a single offset broach handle. Two double offset broach handles (A European version, B American version) were compared to a single off...

The combination of Multiple-Input Multipleoutput (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) has been viewed as the trend of the new wireless LAN technology. In this paper, the design of an up-to-date 2 x 2 Space-Time Block Coded (STBC) MIMOOFDM baseband receiver is presented with reference to an IEEE 802.11 n proposal. To solve possible different carrier frequency offsets betw...

Based on the scenario assumed that the CFO (carrier frequency offset), which is caused by the ICI (inter-carrier interference), exists in the environments of short-term fading, a multi-dimension combining (M-D combining) receiver for an MC-CDMA (multi-carrier coded-division multiple-access) system is designed and proposed considerably to overcome the system performance degradation. It is worthw...

The three electromagnetic properties appearing in Maxwell’s equations are dielectric permittivity, electrical conductivity and magnetic permeability. The study of point diffractors in a homogeneous, isotropic, linear medium suggests the use of logarithms to describe the variations of electromagnetic properties in the earth. A small anomaly in electrical properties (permittivity and conductivity...

Prestack depth migration of shot profiles by downward continuation is a practical imaging algorithm that is especially cost-effective for sparse-shot wide-azimuth geometries. The interpretation of offset as the displacement between the downward-propagating (shot) wavefield and upward-propagating (receiver) wavefield enables us to extract offset-domain common imagepoint (CIP) gathers during shot...
