For the QPSK and 16-QAM cases, we use an infinite series expression for the error function in order to express the average probability of error in terms of the two-dimensional characteristic We will use our precise for-mulas to verify the accuracy of this approach.1) Approximate SNR Degradation: In , the effect of theCFO is characterized as a loss of SNR.

Althoughis not strictly bounded, the probability that real or imaginarypart ofexceeding is verysmall. Secondly, the bit error rate (BER) caused by CFO could be approximated by assuming the ICI to be Gaussian. ASSUMPTIONS AND PROBLEM STATEMENTWe assume an ideal additive white Gaussian noise (AWGN)channel. A.
Probability of symbol error with normalizedfrequency offset,dB for BPSK and dB for QPSK.In Fig. 1, error rates are shown for an OFDM system withfor BPSK andQPSK modulation schemes. It willsoon become evident that the required error probabilities can beexpressed in terms of this function.The CHF ofin this case is(15)We can now evaluate the average value of (14) using this Probability of symbol error for BPSK and QPSK.

Just as withthe QPSK case, the correct decision probability can be writtenas a product of the error function. In addition, the impact of imperfect channel estimation on the overall spectral efficiency is also included.

Previously, two methods were available for the analysis of the resultant degradation in performance. The subcarriers are modulated with binary phase-shiftkeying (BPSK), quaternary phase-shift keying (QPSK), or16-ary quadrature amplitude modulation (16 QAM), which arecommon modulation formats used in OFDM applications. This technical combination offers high cell capacities by exploiting the inherent multiuser diversity effect of the system. Pollet, M.
