To meet the exponentially increasing air traffic, Lband (960-1164 MHz) digital aeronautical communication system (LDACS) has been introduced. The LDACS aims to exploit vacant spectrum between incumbent Distance Measuring Equipment (DME) signals and envisioned to follow multi-carrier waveform approach to support high-speed delay-sensitive multimedia services. This paper deals with the design and implementation of end-to-end LDACS transceiver on Zynq System on Chip (ZSoC) platform, consisting of FPGA as programmable logic (PL) and ARM as processing system (PS). We consider orthogonal frequency division multiplexing (OFDM) based LDACS and improve it further using windowing and/or filtering. We propose hardware software co-design approach and analyze various transceiver configurations by dividing it into PL and PS. We demonstrate the flexibility offered by such co-design approach to choose the configuration as well as word-length for a given area, delay and power constraints. The transceiver is also integrated with the programmable analog front-end to validate its functionality in the presence of various RF impairments and wireless channels and interference specific to the LDACS environment. To the best of our knowledge, this is the first ever in-depth analysis of the performance of end-to-end LDACS transceiver concerning parameters such as out-of-band attenuation, DME interference, bit-error-rate, word-length, area, delay, and power.
