Paper on Maximizing the Throughput for MIMO OFDM-CDMA Systems by Evaluating Space Time Frequency Spreading

The main goal is to access the appropriateness of OFDM as a modulation technique for a fixed wireless phone system. Several of the main factors affecting the performance of a OFDM system, were measured including multipath delay spread, channel noise, distortion of the signal (clipping), and timing requirements. This paper focuses on how MIMO OFDM-CDMA systems are capable of achieving diversity gains significantly larger than that of the day to day system.
