Patent ID: 8098625

Claim:
A wireless terminal comprising: hardware resources of a wireless terminal compatible with an OFCDM (Orthogonal Frequency And Code Division Multiplexing) system, said wireless terminal being reconfigured from a configuration compatible with the OFCDM system to a configuration that is concurrently compatible to communicate with both of an OFDM (Orthogonal Frequency Division Multiplexing) system and a CDMA (Code Division Multiple Access) system with another wireless terminal using common hardware resources of the wireless terminal that are compatible with the OFCDM system, wherein the wireless terminal compatible with the OFCDM system has a synchronous detection section and said synchronous detection section performs synchronous detection compatible with all of the OFCDM system, the OFDM system, and the CDMA system, wherein said synchronous detection section comprises a first synchronous detection section for the OFDM system, a second synchronous detection section for the CDMA system and an adder, and said first synchronous detection section for the OFDM system and said second synchronous detection section for the CDMA system output signals independently when said wireless terminal is in the configuration that is concurrently compatible to communicate with both of the OFDM system and the CDMA system, whereas said first synchronous detection section for the OFDM system and said second synchronous detection section for the CDMA system output signals to said adder so that said adder adds the output signals to each other when said wireless terminal is in the configuration compatible with the OFCDM system.
