The huge demand for broadband remote access has promoted the development of the long-term evolution (LTE). The turbo code is one of the most types of forward error correction code that used in Third Generation Partnership Project (3GPP), which standardization works by LTE. One of the major tasks of 3GPP LTE is to increase the speed of radio access to mobile communications. Rate matching (RM) is an important tool used for adaptive the turbo code rate (CR) to increase the throughput of LTE. This research is attempted to evaluate the LTE-system-based turbo code with various CR and compare the data rate for each one with its amount of bit error rate (BER). An RM algorithm based on interlaced and circular buffer applying for 3GPP LTE system has been added to the system in order to reduce redundancy information, thereby increasing the data rate. Using Matlab R2016a package, the proposed algorithm is evaluated and compared with a conventional system in terms of BER and the amount of throughput. The results confirm that RM can increase the CR from 1/3 to which leads to increase the data rate in the same proportion.
