Multiple access techniques like OFDMA and antenna technology MIMO has been analyzed using modulation\ntechniques BPSK and 16 QAM based on BER and SNR in LTE network. 3G is a very popular technology amongst the\npresent day users, but they still face some drawbacks such as low data rates, coverage area, high cost, and latency leading to\nabrupt call drops which annoys the user. New generation is in search of better Quality of Service, high data rate, reduced\nlatency, large coverage area, high spectral efficiency at an affordable cost. Long Term Evolution (LTE) is the technology\nused in 4G that supports these features. It supports two multiple access techniques namely Orthogonal Frequency-Division\nMultiple Access (OFDMA) and Single Carrier Frequency Division MultipleAccess (SC-FDMA). OFDMA along with MIMO\ntechnology is used for downlink channel and SC-FDMA is used in uplink channel.
