Abstract
Certain embodiments of the present disclosure support techniques for interference cancellation in a multi-mode wireless modem that supports coexistence of different radio technologies.
Claims56
A method for wireless communications, comprising:
- receiving a signal of a second radio technology with interference from a transmission signal of a first radio technology;
- translating the interference into a narrower frequency band to obtain a received signal with narrowband interference;
- and
- filtering the received signal with narrowband interference to obtain a signal without the interference.
An apparatus for wireless communications, comprising:
- logic for receiving a signal of a second radio technology with interference from a transmission signal of a first radio technology;
- logic for translating the interference into a narrower frequency band to obtain a received signal with narrowband interference;
- and
- logic for filtering the received signal with narrowband interference to obtain a signal without the interference.
An apparatus for wireless communications, comprising:
- means for receiving a signal of a second radio technology with interference from a transmission signal of a first radio technology;
- means for translating the interference into a narrower frequency band to obtain a received signal with narrowband interference;
- and
- means for filtering the received signal with narrowband interference to obtain a signal without the interference.
A computer-program storage apparatus for wireless communications comprising a memory having one or more software modules stored thereon, the one or more software modules being executable by one or more processors and the one or more software modules comprising:
- instructions for receiving a signal of a second radio technology with interference from a transmission signal of a first radio technology;
- instructions for translating the interference into a narrower frequency band to obtain a received signal with narrowband interference;
- and
- instructions for filtering the received signal with narrowband interference to obtain a signal without the interference.
