Impact of RF Front-end non-idealities on performances of SIMO-OFDM receiver

This article presents a performance comparison of a single antenna OFDM receiver and a SIMO structure using zero-IF front end topology. The performances evaluation was made in most as possible realistic working conditions. That is why numerical processing is applied on recorded signals, ensuring to take into account antenna coupling, channel correlation and also realistic propagation channel characteristics. Simulated results are also detailed. I/Q imbalance, oscillator phase noise and power amplifier non-linearity are the studied RF impairments.
