Abstract :
This paper presents a reconfigurable inner receiver for the LTE, DVB-H, and IEEE802.11n (WLAN) radio systems, all of which are based on orthogonal frequency division multiplexing (OFDM). The receiver is implemented in the CAL language. An FPGA-based hardware implementation is synthesized from RTL generated from the CAL description. The purpose of our work is to investigate the feasibility of dataflow methodology for high-level description of digital radio transceivers.
