Multiple Input Multiple Output (MIMO) transmission system is one of the recent and the most promising technology which uses multiple antennas in the transmitter as well as receiver side and is currently used for high-rate wireless communication. However, Multi-path propagation leads to IS! in MIMO wireless receiver. To eliminate ISI we need to equalize the received signal. Equalizers like Zero forcing...
This paper presents the impact of phase noise on the performance of a communication link with QPSK digital modulation. For example, how phase noise affects bit error rate is demonstrated with detailed simulations. Also, this paper illustrates how phase noise affects the receiver signal constellation diagram and employs a model for simulating the phase noise. More importantly, this paper shows clearly...
Abstract-This paper presents a new way to realize the dynamic model of MIMO channel in presence of m-Nakagami fading. The dynamic model is compared with the static model of MIMO channel and the performance analysis of SISO, SIMO, MISO and MIMO systems is evaluated in presence of m-Nakagami distribution. All the results are plotted between signal to noise ratio (SNR) and bit error rate (BER) which...
In an library based waveform (WF) development for software defined radios, high-level performance estimation models of implementations are beneficial for converging quickly to an optimal mapping of a WF-description to a hardware platform. A model that estimates the changes in performance, e.g. bit error rate (BER), due to the configuration-parameters, e.g. input data-width, in implementations is helpful...
An 11.8 Gb/s transceiver with 3-tap FIR TX and adaptively equalized RXis implemented in a 32 nm CMOS process. The RX features a continuous-time LE with AGC, a 4-tap DFE and baud-rate timing recovery. The transceiver achieves a BER<2 ?? 10-15 with PRBS23 over a 24" PCB trace with 25 dB loss at 5.9 GHz. The TX/RX lane occupies 0.155 mm2 and consumes 78 mW from a 0.95 V supply when operating...
Using a 7.5 ??m wide InP Micro-Disc-Laser, with a very low ~100 ??A threshold current, heterogeneously integrated on top of Silicon on Insulator substrate, all optical NRZ wavelength conversion at speeds up to 20 Gb/s is demonstrated.
This paper presents a detailed analysis of the distortion effects of the power amplifier nonlinearity on the bit error rate (BER) performance of a band limited digitally modulated signal present at the amplifier input. Previous analyses of such distortion effects are mainly concerned with the total distortion power present at the amplifier output and in some cases present results on the amplifier...
The paper presents a novel and robust adaptive receiver that jointly estimates the fading amplitude distortion induced by Rayleigh fading channels, as well as the carrier phase noise that is contributed by the receiver local oscillator (LO) and the fading channel. The amplitude fading estimate is used by a novel phase estimator which also involves data detection. The phase noise estimate is input...
The performance of band limited M-ary PSK communication systems is impacted by amplifier nonlinearities. It is critical to precisely model high-power amplifiers (HPAs) to ascertain the bit error rate (BER) performance of M-ary PSK communication systems, which are band limited. State-of-the-art simulation techniques can be employed to exactly ascertain intersymbol interference (ISI) and its degradation...
