Coordinated multi-point transmission and reception (CoMP) is introduced in LTE-A to mitigate co-channel\udinterference and improve the cell-edge user experience. In this paper we propose a joint transmission\udscheme for LTE-CoMP and we enhance the performance of CoMP with two techniques: 1- dynamic MIMO\udcell selection and 2- closed loop MIMO with global precoding matrix selection. A cell-edge user selects the\udbase stations that jointly transmit the desired signal from the available ones (we assumed 3). The user also\udselects the closed loop precoding matrices for MIMO in a joint fashion to fit the independent MIMO\udchannels from two base stations (eNBs). In addition, edge users are likely to be subject to severe Cochannel\udinterference from eNBs outside the joint transmission set.To address co-channel interference from\udthe base station(s) that are not included in CoMP joint transmission set, the user equipment employs\udMinimum Mean Squared Error receiver with Interference Rejection Combining (MMSE-IRC). We illustrate\udthe effect of fading correlation between elements of the transmit and receive antennas. Also, the effect of\udthe desired to interference eNB power ratio in case of medium correlation for 3 and 4 layers using MMSEIRC\udreceiver is studied. Also we compare the BER performance for 3 and 4 layers in case of different\udvalues of the desired to interference eNB power ratio. Simulation results show that the performance of\udCoMP with cell selection considerably improves the performance. Also, global selection of the precoding\udmatrices outperforms local selection. In addition, using MMSE-IRC gives much better performance than\udthe conventional minimum mean square error (MMSE) in the presence of co-channel interference. \u
