3 Bit Error Rate International Journal of Scientific & Engineering Research Volume3, Issue 1, January Equal Gain Combining (): All the received signals are summed coherently. With two receive antennas, the BER with equal gain combining is... (6) The effective with is Figure 3 QAM modulator 4.2 Maximal Ratio Combining ():... (7) It is often used in large phased array systems. The received signals are weighted with respect to their and then summed. The resulting yield where is of the received signal k. Given that the effective bit energy to noise ratio with maximal ratio combining is, the total bit error rate is the integral of the conditional BER integrated over all possible values of. The effective 5 QAM with is. (8) (9) Quadrature amplitude amplitude (QAM) conveys two digital bit streams by changing the amplitudes of two carrier waves using amplitude shift keying. These two sinusoidal waves are out of phase with each other by 90 degrees. The in-phase signal (the I-signal, e.g., cosine waveform) and a quadrature phase signal (the Q-signal, e.g., sine waveform) are amplitude modulated with a finite number of amplitudes and summed, resulting a combination of phase shift keying and amplitude shift keying. The QAM equation is represented as follow in equation 2 2 s( t) Ac cos( ( t))cos(2 f ct) Ac sin( ( t))sin(2 f ct) T T Where 2. (10) M For a 4-QAM signal, we have M = 4, so we have 4 symbols representing a two bit word. Therefore, for M = 16 and 64, we have 16 symbols representing a four bit word and 64 symbols representing a six bit word respectively. The bit error probability expressed in equation is M-ary QAM 1 3 p e 4(1 ). T.. M M 1 6 RESULT p e E No for M-ary QAM is (11) If we set the simulation environment for the OFDM based wireless modulation, then we get the variable performance for equalizers as well as for diversity techniques. The following results have been obtained with the considered combinations. Figure 1, shows the effect of 256 OFDM subchannels, 4 QAM with 1000 number of iterations. BER with '','','','' and with 256 subchannels, 4 QAM and 1000 iterations Figure

4 Bit Error Rate Bit Error Rate Bit Error Rate International Journal of Scientific & Engineering Research Volume3, Issue 1, January Figure 2, shows the effect of 1024 OFDM subchannels, 4 BER with '','','',' and with 1024 subchannels, 4 QAM and 1000 iterations Figure 4, shows the effect of 1024 OFDM subchannels, 32 BER with '','','',' and with 1024 subchannels, 32 QAM and 1000 iterations Figure Figure 3, shows the effect of 512 OFDM subchannels, 32 BER with '','','','' and with 512 subchannels,32 QAM and 1000 iterations Figure CONCLUSION The wireless communication without the channel estimation results in high errors. Therefore channel estimation is most important to know the parameters of the channel and also to get the knowledge of affecting parameters Figure If we look at the simulation result with 1024 sub channels and 1000 iterations, we find that the BER curve is becoming linear and therefore with high number of subcarriers and with 1000 iterations we get better results compared to 256 and 512 sub channel conditions. One thing is clear here that with lower order QAM modulation techniques results are not much comparative, but results in bunching like the optimum performers. Only the change between performances can be seen with lower number of subcarriers and with 1000 iterations.

5 International Journal of Scientific & Engineering Research Volume3, Issue 1, January Therefore we conclude with this assumption that with 1000 iterations we have better performance of used algorithms and is very much able to show expected results.
