A wireless communication technique enables fast Fourier transforms (FFTs) and inverse fast Fourier transforms (IFFTs) to be performed with reduced latency and reduced memory requirements. In particular, an FFT/IFFT unit receives input data representative of a communication symbol. The FFT/IFFT unit applies an FFT operation to the input data to generate intermediate data. The FFT/IFFT unit stores the intermediate data in a random access memory (RAM). The intermediate data stored in the RAM may override data used as input to the FFT operation. The FFT/IFFT unit selectively addresses the RAM to retrieve the intermediate data in a desired output order. For example, the FFT/IFFT unit may output the intermediate data in the same sequential order as the FFT/IFFT unit received the input data.
