Embodiment Construction
[0070] The present invention provides a method for TD-SCDMA compatible OFDM technology, and the specific scheme is as follows: In the TD-SCDMA system, in order to ensure the reliable transmission of data on the wireless link, the physical layer first needs to perform the data flow from the MAC and the upper layer. Coding / multiplexing, and after physical channel mapping, the data on the channel will be spread spectrum and scrambled. Spread spectrum multiplies the channel data by a sequence of numbers higher than the data bit rate. The result of the multiplication expands the bandwidth of the signal, converting the bit rate data stream to a chip rate data stream. Spread spectrum processing is also commonly referred to as channelization operation, and the sequence of numbers used is called a channelization code, which is a set of codes that can vary in length but still be mutually exclusive. The scrambling code is similar to the spread spectrum, and it also uses a digital sequenc...
