In the era of digital wireless communication, applications of wavelet theory have been favorably applied in many areas of signal processing. Orthogonality, flexible time-frequency analysis, and the ability to characterize signals accurately have attracted the attention of the telecommunication community to use wavelet as a basis function for OFDM. In this paper, discrete wavelet transform (DWT) has been proposed as an alternative signal analysis with multiple merits such as support high-speed applications, immune to distortion, wavelet diversity, better error performance, and efficient bandwidth utilization. A simulative analysis of various wavelets, at different modulation techniques, over OFDM has been presented to demonstrate the improvement in BER performance. Further, in accordance with the LTE parameterization over 1.25\u2009MHz band, the performance of wavelet-based OFDM (WOFDM) is found significantly higher in terms of maximum achievable data rate and system spectral efficiency.<\/jats:p>","DOI":"10.1155\/2020\/8835879","type":"journal-article","created":{"date-parts":[[2020,12,1]],"date-time":"2020-12-01T16:52:11Z","timestamp":1606841531000},"page":"1-9","source":"Crossref","is-referenced-by-count":1,"title":["Analysis of WOFDM over LTE 1.25\u2009MHz Band"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7236-1556","authenticated-orcid":true,"given":"Sandeep","family":"Sarowa","sequence":"first","affiliation":[{"name":"CERT-In, MeitY, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5677-971X","authenticated-orcid":true,"given":"Naresh","family":"Kumar","sequence":"additional","affiliation":[{"name":"UIET, PU, Chandigarh, India"}]},{"given":"Ram Sewak","family":"Singh","sequence":"additional","affiliation":[{"name":"ASTU, Adama, Ethiopia"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1007\/0-387-30235-2"},{"volume-title":"Orthogonal Frequency Division Multiplexing for Wireless Communications","year":"2009","author":"Y.
