This thesis studies implementation-related issues in OFDM-based digital receivers, using the IEEE 802.11a WLAN standard as a specific wireless technology, where the data rate ranges from 6 Mbps to 54 Mbps. Our goal is to expose and exploit the possibility of scaling of the receiver computational complexity in relation to variable data rate requirements. To facilitate such computational scalability, we propose and evaluate the use of the polar coordinates during data processing in the frequency domain. We also evaluate the impact of various fixed-point precision settings during data processing in both the time domain and the frequency domain. We have found that for the 6-Mbps and 54-Mbps data rates the appropriate fixed-point word length should be 15 bits and 20 bits, respectively. While evaluating different fixed-point precision settings, we found that simulations times were prohibitively long. To address this issue, we also propose an alternative 5-step simulation procedure that significantly reduces the simulation time needed to evaluate any given fixed-point setting option. / Graduate
