In this algorithm, to compute the ODCT coefficients of a real\u2010time sequence, we do not require the ODST coefficients. Similarly, the ODST coefficients of the shifted sequence can be calculated without using ODCT coefficients. The running input data sequence is sampled using a rectangular window. However, this idea can be easily extended for other windows. The update algorithm derived herein can be used to compute the transform coefficients of the shifted sequence as new data points are available. The complexity of developed algorithm is <jats:italic>O<\/jats:italic>(<jats:italic>N<\/jats:italic>). The validity of algorithm is tested by MATLAB simulations.<\/jats:p>","DOI":"10.1155\/2012\/879626","type":"journal-article","created":{"date-parts":[[2012,12,13]],"date-time":"2012-12-13T21:02:58Z","timestamp":1355432578000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Improved Algorithm for ODCT Computation of a Running Data Sequence"],"prefix":"10.1155","volume":"2012","author":[{"given":"S.","family":"Akhter","sequence":"first","affiliation":[]},{"given":"V.","family":"Karwal","sequence":"additional","affiliation":[]},{"given":"R.
