Abstract

Orthogonal frequency division multiplexing (OFDM) has been identified as one potential method to enhance the performance of wireless communication links degraded by cosite interference, impulsive noise, and frequency-selective fading. In the past, implementation complexity slowed the development of OFDM for useful commercial and handheld applications. With the advances in semiconductor processing technology and digital signal processing, OFDM is now practical for system solutions including wireless LANs, audio and television broadcasting, and land mobile services. We describe the application of OFDM within software defined radio (SDR) platforms to provide multi-service land mobile radio capabilities. The simple combination of OFDM and SDR provides great flexibility in system configuration, significant reduction in product development cycle time, and very high potential for software reuse
