Description

technical field

[0001] The invention relates to a wireless mobile communication system, in particular to an upgradeable OFDM transceiver based on software radio. Background technique

[0002] Orthogonal Frequency Division Multiplexing (OFDM for short) has become one of the most competitive wireless communication technologies. There are many literatures discussing OFDM system design and implementation schemes, and this technology has been applied in practical systems (such as 802.11, 802.16 series). OFDM can divide the wideband spectrum into many small narrowband sub-carriers, which can transmit high-speed data signals in a wireless multi-user environment. In particular, this technology will attract more attention from the world as an effective means of next-generation wireless mobile communication.

[0003] Along with technological progress and increasing people's needs, the requirements for mobile communication systems in home and office are also increasing. In the cellu...
