Mission statement:

3GPP group standardized Long Term Evolution (LTE) and it is designed to have transmission bandwidth up to 20MHz, with low latency and packet optimized radio access technology. The maximum data rate contemplated for LTE is 100 Mbps in downlink and 50 Mbps in the uplink. The 3GPP selected Orthogonal Frequency Division Multiple Access as the radio access technology because it can be simply implemented in receiver with high performance and high spectral efficiency. The performance of LTE PHY layer can be measured in terms of BER, and channel capacity. In this case study, students will build a multi-cell network, where users are randomly scattered in the cells. The interference is calculated and considered to compute the channel capacity of individual users.

Work Guidelines:

1. Use the Matlab scripts to build up your code. However, you have the freedom to change the propagation model as preferred.

2. Model three cells in your LTE networks, such that in each cell, a total of 100 users are randomly distributed in each cell.

3. Compute the Shannon capacity (C) in b/s for every user based on SINR and the following formula, assume the system bandwidth (BW) is 10 MHz.

C=BW*log2(1+SINR)

4. In order to run your project, you need to decide on the following:

a. Path loss model.

b. The optimum cell size to achieve an acceptable SINR levels. Assuming the transmit power for all BSs 39dBm.

5. In the results section, provide the following:

a. CDF of SINR for the three cells in one graph.

b. CDF of the capacity for the three cells in one graph.

6. discuss the following:

a. Include all code scripts used with relevant discussion.

b. Explain the path loss used.

c. Justify the choice of cell size.

d. Included all required references.
