Bit-error probability of QPSK with noisy phase reference
IEE Proceedings - Communications, 1995An approximate result is obtained for the bit-error probability of quadriphase shift keying in the presence of additive white Gaussian noise and a Tikhonov distributed-phase-reference error. The accuracy of the approximation is verified via actual numerical integration of the bit-error-probability formula.

Asymptotic bit error probabilities of some closed-loop transmit diversity schemes
Global Telecommunications Conference, 2002. GLOBECOM '02. IEEE, 2003Transmit diversity techniques have received a lot of attention recently, and open-loop and closed-loop downlink transmit diversity modes for two transmit antennas have been included in the 3GPP WCDMA Release 5. System capacity can be increased from that of open-loop modes if the transmitter can be provided additional side information of the downlink ...

Bit error probability analysis for FRAMES WCDMA downlink receivers
IEEE Transactions on Vehicular Technology, 1998The wide-band code-division multiple-access (WCDMA) concept FMA2 developed in the European Future Radio Wide-Band Multiple-Access Systems (FRAMES) project supports variable-data-rate transmission. The data rate can be altered by changing either the spreading factor or by using multiple spreading codes in parallel.

Bit error probability analysis of UWB communications with a relay node
IEEE Transactions on Wireless Communications, 2010In this paper, the extension of cooperative communication to the context of TH-UWB is investigated. In particular, the average bit error probability (BEP) is provided for cooperative TH-UWB systems with decode-and-forward relaying protocol. In the considered relay network, UWB links among the nodes are modeled according to IEEE 802.15.4a standards. Our

Bit-Error Probability for Orthogonal Space–Time Block Codes With Differential Detection
IEEE Transactions on Communications, 2004Explicit closed-form expressions of the bit-error probabilities are obtained for space-time block codes based on generalized orthogonal designs with differential encoding and differential detection using 2/sup b/-ary phase-shift keying mapping. The frequency-nonselective, block-wise constant Rayleigh fading channel is considered here.

Computation of Bit-Error Probability Using the Trapezoidal Integration Rule
IEEE Transactions on Communications, 1974It is shown in this paper that bit-error probabilities for some typical digital communication systems can be accurately and efficiently evaluated using the elementary trapezoidal integration rule. Examples involving intersymbol interference and a Rayleigh fading channel are worked.

MC-CDMA bit error probability and outage minimization through partial combining
IEEE Communications Letters, 2005This work addresses the performance evaluation, in terms of bit error probability (BEP) and bit error outage (BEO), for the down-link of multi-carrier code division multiple access systems. A partial combining technique depending on a parameter adapted to the system load and the mean signal-to-noise ratio is proposed to counteract both interference and
