Abstract

The performance of a noncoherent decoder based on a pair of distributed‐based transversal filters architecture is reported. Analysis based on experimental results validates the decoder as a proof‐of‐concept using microwave integrated circuits. Front‐end transversal filters are designed with large degree of freedom to generate and correlate temporal phase‐coded signals. Receiving functions are aligned with slots of spectrally encoded channels to make available spectral amplitude‐coding electronic‐code division multiple access. Noncoherent ultra‐wideband receiver concepts are applied to model the decoder synchronized to shot noise pulse trains. The despreading operation involves capturing sufficient amount of energy to demodulate matched and unmatched users. Electronic transversal filters implemented with a suitable number of taps allow bipolar detection of concurrent users whereas the noncoherent reception of energy of sub‐bands is fundamental to achieve orthogonality among channels, as we show in this article.
