A promising approach for future wireless communications, including 6G and beyond, is to unify these waveforms to accommodate diverse operating conditions and user requirements. However, processing multiple computationally intensive waveforms on a traditional Application-Specific Integrated Circuit\u00a0(ASIC) is impractical due to its fixed design. In contrast, Coarse-Grained Reconfigurable Array\u00a0(CGRA), a typical class of reconfigurable architectures, provides greater flexibility and efficiency, making it a more feasible alternative for such demanding workloads. In this paper, we propose a unified modulator framework that integrates five different waveforms onto a single CGRA platform. This approach demonstrates the run-time reconfiguration capabilities of CGRAs, enabling seamless switching between waveforms to support a unified modulation model. To optimize execution, this work explores overlapping computational and memory-access patterns for the target waveforms, enhancing performance and efficiency. For evaluation, the proposed design is synthesized on a Stratix-IV FPGA device and compared against existing implementations that focus on fixed, single-waveform architectures. The unified modulator implementation achieves an operating frequency of 170.0\u00a0MHz, a throughput of 10.88\u00a0GOPS and a dynamic power dissipation of 528\u00a0mW. Additionally, the scalability of the proposed approach is evaluated across various input sizes\u00a0(8\n                    <jats:inline-formula>\n                      <jats:tex-math>$$\\times$$<\/jats:tex-math>\n                    <\/jats:inline-formula>\n                    4, 8\n                    <jats:inline-formula>\n                      <jats:tex-math>$$\\times$$<\/jats:tex-math>\n                    <\/jats:inline-formula>\n                    8, 16\n                    <jats:inline-formula>\n                      <jats:tex-math>$$\\times$$<\/jats:tex-math>\n                    <\/jats:inline-formula>\n                    16), demonstrating its flexibility with promising results.\n                  <\/jats:p>","DOI":"10.1007\/s11265-025-01975-6","type":"journal-article","created":{"date-parts":[[2026,2,6]],"date-time":"2026-02-06T04:46:28Z","timestamp":1770353188000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Towards Unified Modulator for Mobility Scenarios: A CGRA-Based Approach"],"prefix":"10.1007","volume":"98","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-1349-2354","authenticated-orcid":false,"given":"Zohaib","family":"Hassan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0295-9912","authenticated-orcid":false,"given":"Waqar","family":"Hussain","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3412-1639","authenticated-orcid":false,"given":"Aleksandr","family":"Ometov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1718-6924","authenticated-orcid":false,"given":"Elena Simona","family":"Lohan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2169-4606","authenticated-orcid":false,"given":"Jari","family":"Nurmi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,2,6]]},"reference":[{"key":"1975_CR1","doi-asserted-by":"crossref","unstructured":"You, C., Cai, Y., Liu, Y., Di Renzo, M., Duman, T.
