Bit Error Rate Performance of QPSK Modulation and OFDM-QPSK with AWGN and Rayleigh Multipath Channel

In this paper Bit Error Rate performance of QPSK modulation and OFDM -QPSK System over AWGN and Rayleigh fading channel is analyzed. The performance of BER of QPSK over AWGN and Rayleigh channel is compared. OFDM is an orthogonal frequency division multiplexing to reduce intersymbol interference problem. Simulation of QPSK signals is carried with both AWGN and Rayleigh channel. Finally simulati...

VLSI implemented ML joint carrier phase and timing offsets estimator for QPSK/OQPSK burst modems

A high performance ASIC supporting multiple modulation, error correction, and frame formats is under development at Hughes Network Systems, Inc. Powerful and generic data-aided (DA) estimators are needed to accommodate operation in the required modes. In this paper, a simplified DA maximum likelihood (ML) joint estimator for carrier phase and symbol timing offset for QPSK/OQPSK burst modems and...

Bit Error Rate (ber) Performance Analysis of Carrier Interferometry Codes in a Cognitive Radio(cr) Environment

Multi Carrier Code Division Multiple Access (MC-CDMA) and Orthogonal Frequency Division Multiplexing (OFDM) are the two most efficient multiple access techniques in a multiuser environment. However, Multiuser Interference (MUI) and Co-Space Interference (CSI) are the two major challenges when multiple antennas are deployed at the transmitter and receiver ends. Moreover, in a Cognitive Radio (CR...

Qpsk, Oqpsk, Cpm Probability of Error for Awgn and Flat Fading Channels [4]

This article discusses QPSK, OQPSK, π/4 DQPSK and the trade offs involved. Later we discuss various CPM schemes and their relative bandwidth efficiencies. Probability of Bit error is discussed for various schemes assuming an AWGN channel. A model is devised, ignoring any changes in phase, to determine the error probabilities for flat fading channels. The article ends with a brief discussion of ...
