摘要： A multimode wireless communication includes a digital baseband processing module, an analog to digital converter module, a digital to analog converter module, a first radio section, and a second radio section. The digital baseband processing module is operably coupled to convert outbound data into outbound digital baseband signals and to convert inbound digital baseband signals into inbound data. The analog to digital converter module is operably coupled to convert inbound analog baseband signals into the inbound digital baseband signals. The digital to analog converter module is operably coupled to convert the outbound digital baseband signals into outbound analog baseband signals. The first radio section is operably coupled to convert the outbound analog baseband signals into first outbound radio frequency (RF) signals and to convert first inbound RF signals into the inbound analog baseband signals when the wireless communication device is in a first mode of operation. The second radio section is operably coupled to convert the outbound analog baseband signals into second outbound RF signals and to convert second inbound RF signals into the inbound analog baseband signals when the wireless communication device is in a second mode of operation.

摘要： A programmable transmitter generates a frame in a frame format according to one of a plurality of operating modes using a frame structure table storing a respective frame format for each of the operating modes. The transmitter includes a frame structure engine that receives a mode selection signal indicative of a select operating mode, and accesses the frame structure table to determine the frame format of the select operating mode. The frame structure engine produces a control signal to a frame generator to control the generation of a frame in the frame format of the select operating mode.
