Abstract
- In order to provide backhaul link wirelessly for emerging convergence services, we develop an OFDM-based backhaul system operating in the E-band channel. Firstly, we make our own backhaul specification considering the E band channel in which the proposed backhaul system operates, where LDPC, 1024-QAM and 2-stream transmission using dual polarizations are adopted. Based on the specification, we simulate the PER performance on AWGN and modified 3GPP channel environment respectively and implement the backhaul system on FPGA (Xilinx Virtex UltraScale xcvu440). To compensate the RF impairments, several baseband signal processing techniques such as phase tracking, IQ balancing and XPIC are used. The backhaul system we develop can support up to 25Gbps throughput in a 2GHz channel bandwidth.
