“…7a. We implement a configurable packet detector using a normalized auto-correlation algorithm [11,14] which detects the periodic sequences used for packet preambles [31,33]. The block is flexible to be used with different preambles with different periods of repetitive sequences, and different SSR factors for different sampling frequencies.…”

The performance of wireless communication systems is evolving rapidly, making it difficult to build experimentation platforms that meet the hardware requirements of new standards. The bandwidth of current systems ranges from 160 MHz for IEEE 802.11ac/ax to 2 GHz for Millimeter-Wave (mm-wave) IEEE 802.11ad/ay, and they support up to 8 spatial MIMO streams. Mobile 5G and beyond systems have a similarly diverse set of requirements.To address this, we propose a highly configurable wireless platform that meets such requirements and is both affordable and scalable. It is implemented on a single state-of-the-art FPGA board that can be configured from 4x4 mm-wave MIMO with 2 GHz channels to 8x8 MIMO with 160 MHz channels in sub-6 GHz bands. In addition, multi-band operation will play an important role in future wireless networks and our platform supports mixed configurations with simultaneous use of mm-wave and sub-6 GHz. Finally, the platform supports real-time operation, e.g., for closed-loop MIMO beam training with low-latency, by implementing suitable hardware/software accelerators. We demonstrate the platform's performance in a wide range of experiments. The platform is provided as open-source to build a community to use and extend it.

“…For reliable system operation these two effects have to be compensated. The CPE is typically estimated per OFDM symbol using pilot subcarriers known to receiver and corrected by de-rotation in frequency domain of all the subcarriers by the estimated phase error and has relatively simple implementation, [3], [12]- [23]. The estimation and compensation of the PN induced ICI is much more complex and in some cases is impractical for implementation in the high data rate hardware architecture used in the IEEE 802.11ay system.…”

“…Therefore, the baseband hardware architecture has high parallelization factor and typically demodulates 8 or 16 subcarriers per clock. Beyond that, there is a strict requirement on the processing delay per hardware block, typically estimated equal to ~100 ns, which makes the implementation of the complicated PN ICI compensation algorithms impractical, [21]- [23].…”

“…The hardware architecture is designed with an 8 times parallelization factor to reduce the maximum baseband operating clock frequency from 2.64 GHz to 330 MHz. The ICI impact is not compensated which makes the 64-QAM OFDM transmission non-reliable with Bit Error Rate (BER) performance exhibiting error floor behavior for the typical channel models adopted in the IEEE 802.11ad (see [22] and [23]).…”

This paper presents a method for phase noise impact compensation in 60 GHz OFDM receivers and provides the results of performance evaluation using OFDM PHY parameters defined in the IEEE 802.11ay standard. It is shown that the phase noise in 60 GHz band has a critical impact on the OFDM performance for high data rate transmission employing high order modulation constellations. The proposed compensation method combines time domain algorithm predicting the linear average phase trend on the OFDM symbol duration and estimation in frequency domain of phase noise spectrum realization and convolution with correction filter response. Both algorithms use Maximum A Posteriori Probability (MAP) estimation approach to find the optimal solution and are applied successively. The proposed algorithms have moderate implementation complexity which is especially important for high speed 11ay hardware modem architecture. The performance of the proposed algorithms is evaluated in the frequency flat and frequency selective channels with phase noise model adopted in the IEEE 802.11ay.
