Abstract: This article introduces a new method of self-cancellation (modified technique of self-cancellation) using a zero gab self- cancellation methodology. In the technique suggested, zero sub-carriers are often used to mitigate the interference of the two neighboring sub-carriers main lobes in addition to zero subcontractors and the method being proposed also used to limit the impact of other sub-carriers side lobes. The modified self-cancelling technology provides the best performance in respect of the CIR and the Bit-Error (BER) ratio only compared with the conventional technique. The adder module interference estimator also often needs data path units in this paper. Mostly as a result, a detailed explanation is still based on increasing the delay in capacity of the adder. The Ripple adductor and the output of the skip adder of each step depends on the previous carrier, but once it is returned to hold tree adders, it produces the transmission signals in O(log n) time and is regarded to have been the simplest and best VLSI output. The Kogge-Stone, Sparse Kogge-Stone and spanning tree adder are compared to the Ripple Carry Adder (RCA).
