Abstract

A system and a method of using fast Fourier transform (FFT) based tone interleaver for OFDM are disclosed. One embodiment of the system includes an OFDM transmitter, which includes an inverse fast Fourier transform (IFFT) subsystem. The IFFT subsystem includes a bit-reversal (or quarternary-digit reversal depending on implementation) module followed by a butterfly operator. The bit-reversal (or quarternary-digit reversal) module output is connected to the butterfly operator input. The OFDM transmitter further includes a tone interleaver having an input and an output. The symbol interleaver output is connected to the bit reversal (or quarternary-digit reversal) module input. The tone interleaver is configured to rearrange the input symbol sequence such that the symbol sequence input to the tone interleaver input is the same as the symbol sequence input to the butterfly operator input.

Description

technical field [0001] The present invention relates to the wireless transmission of video information, and more particularly, to the transmission of uncompressed high-definition video information over wireless channels. Background technique [0002] With the development of high-quality video, an increasing number of electronic devices, such as consumer electronic devices, utilize high-definition (HD) video, which may require gigabits per second (Gbps) of bandwidth, for transmission. Therefore, when sending these HD videos between devices, traditional transmission methods compress the HD video to a fraction of its size to reduce the required transmission bandwidth. Subsequently, the compressed video is decompressed for consumption. Contents of the invention [0003] technical problem [0004] However, with each compression and subsequent decompression of video data, some data is lost and image quality degrades. [0005] The High-Definition Multimedia Interface (HDMI) sp...
