Abstract
A method is provided for operating a wireless device. In this method, a first operation is performed on a wireless signal using a first group of wavelets arranged according to a first analog code word format (720). A second operation is then performed on the wireless signal using a second group of wavelets arranged according to a second analog code word format (740). The first code word format can be different in content and in size from the second code word format. By choosing different properties for each analog code word format, the device can optimize the performance of each operation. These operations can be performed in receiving process (800) or a transmission process (900).
Claims22
A method for operating a wireless receiver, comprising:
- performing a first operation on a received wireless signal using a first plurality of wavelets arranged according to a first analog code word format;
- and
- performing a second operation on the wireless signal using a second plurality of wavelets arranged according to a second analog code word format, after performing the first operation,
- wherein the first analog code word format is different from the second analog code word format.
A method for operating a wireless transmitter, comprising:
- transmitting a first plurality of wavelets arranged according to a first analog code word format, for use in a first operation at a wireless receiver;
- and
- transmitting a second plurality of wavelets arranged according to a second analog code word format, after transmitting the first plurality of wavelets, for use in a second operation at the wireless receiver,
- wherein the first analog code word format is different from the second analog code word format.
A wireless device, comprising:
- a plurality of stored code word registers for providing a plurality of first multiplexer input signals;
- p1 a first multiplexer for choosing one of the plurality of first multiplexer input signals to pass as a first multiplexer output signal;
- a plurality of operational code word registers for selectively receiving the first multiplexer output signal from the first multiplexer, and for providing a plurality of second multiplexer input signals;
- and
- a second multiplexer for choosing one of the plurality of second multiplexer input signals to pass as a second multiplexer output signal,
- wherein each of the plurality of operational code word registers stores a code word for use in a different operation in the wireless device.
