Özet
It is preferable for wireless operators to use the existing infrastructure as possible for different services such as GSM, 3G and Wimax. This becomes possible with the development of software defined base stations. But, to obtain desired performance and flexibility in signal processing at software defined base stations needs to be implemented instead of traditional processors and ASIC modem on programmable processors. The purpose of this thesis is implementing of the OFDM modem architecture on FPGA by using IEEE-754 floating point and IQ-Math fixed point number format. Two different OFDM modem design implemented by using IEEE-754 and IQ-Math, compared with basis of the usage of FPGA hardware resources, design clock frequency and the sensitivity of number formats criteria. © 2013 IEEE.
