This paper aims to evaluate the performance obtained by the V-BLAST detection algorithm in MIMO (Multiple-Input Multiple-Output) systems. The simulations will be performed by writing lines of code in the Matlab simulation environment. Consider a MIMO system in a configuration with 2 transmitting antennas and 2 ...used (BPSK, QPSK) when the channel is affected by different types of fading (Rayleigh, Rice ) and Code Division Multiple Access (CDMA) using real spread codes (Walsh-Hadamard and PN). Different types of equalizers will be implemented at the reception. The evaluation of the performance of the system in question will be performed by drawing graphs of the bit error rate according to the signal-to-noise ratio that will highlight the advantages and disadvantages of each proposed...
