Simultaneous Reception of Multiple Modulation Schemes

摘要

A multichannel radio receiver is configured to define at least two channel plans, each channel plan having at least one channel. The channel plans may differ due to channel bandwidths, channel locations, channel number and/or channel spacings. At least a portion of a radio spectrum may be common to at least two of the channel plans. At least two decoders may operate simultaneously to decode different modulation schemes on each of the at least two channel plans. In one example, two channel plans overlap portions of the radio spectrum. Two different and complementary modulation schemes are used on the two channel plans, respectively. The complementary modulation schemes reject signals associated with the other. Accordingly, portions of the radio spectrum are used simultaneously by at least two channel plans and at least two modulation schemes, respectively.
