Bit Error Rate (BER) and Bit Energy to Noise Ratio performance of the 1-D RAKE receiver without , with Space Time Transmit Diversity (STTD) and 2-D RAKE without , with (STTD) and also without and with beamforming for WCDMA over Rayleigh Channel in presence of Additive White Gaussian Noise (AWGN) channel is demonstrated with purpose of making simulation of m-files developed in Matlab.Results are evaluated in terms of BER and  considering the number of Base Station (BS) transmit antennas (1-D RAKE and 2-D RAKE receivers), and the number of RAKE fingers (1-D RAKE receiver) and the number of Mobile Station (MS) receive antennas (2-D RAKE receiver). The performance results of 1-D RAKE and 2-D RAKE receivers showed that the receivers have satisfactory BER performance and the performance of RAKE receivers is more improved by increasing the number of RAKE fingers, performance is even better when beamforming was applied. The performance results of the three receive diversity of 2-D RAKE receiver schemes: Selection Combining (SC), Equal Gain Combining (EGC) or Maximal Ratio Combining (MRC)) of 2-D RAKE showed that there are significant improvements in BER and  performance over the 1-D RAKE . BER of 10 can be obtained at ≤ 5 dB performance with four fingers of 2-D RAKE receiver with STTD and beamforming and MRC scheme for five receive antenna elements.
