in the accompanying drawings and detailed in the following description descriptions of well known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein the examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein accordingly the examples should not be construed as limiting the scope of the embodiments herein as mentioned there remains a need for reducing the complexity of interleaver design and at the same time reduce the interleaver area the embodiments herein achieve this by providing systems and methods for dividing the current symbol count by the buffer size corresponding to the current input carrier index where the resulting modulo output representing the exact intra buffer offset it should be also noted that mode 1 is used as an example and the same idea described in the disclosure can be applicable to mode 2 and mode 3 for both the architectures described below referring now to the drawings and more particularly to fig1 through 5 where similar reference characters denote corresponding features consistently throughout the figures there are shown preferred embodiments an isdb t transmitter employs time interleaving to randomize modulated ofdm symbol data in time domain in order to ensure robustness against fading interference a convolutional interleaving scheme is used in which every data carrier in an ofdm symbol is fed into a delay buffer of depth where i.
