An apparatus including signal conversion circuitry for converting a multiple input, multiple output (MIMO) packet data signal transmission to a plurality of data samples, comprising:
- input signal conversion circuitry responsive to at least first and second radio frequency (RF) signals and at least first and second local oscillator (LO) signals by converting said at least first and second RF signals to at least first and second frequency converted signals, wherein said at least first and second RF signals have a common RF carrier frequency, include at least first and second data streams, and form at least a portion of a MIMO packet data signal transmission;
- signal combining circuitry coupled to said input signal conversion circuitry to combine said at least first and second frequency converted signals to provide at least one combined signal;
- and
- output signal conversion circuitry coupled to said signal combining circuitry and responsive to said at least one combined signal by providing a plurality of data signals having a common nominal frequency and including data samples corresponding to said at least first and second data streams.
An apparatus including signal conversion circuitry for converting a multiple input, multiple output (MIMO) packet data signal transmission to a plurality of data samples, comprising:
- input signal converter means for responding to at least first and second radio frequency (RF) signals and at least first and second local oscillator (LO) signals by converting said at least first and second RF signals to at least first and second frequency converted signals, wherein said at least first and second RF signals have a common RF carrier frequency, include at least first and second data streams, and form at least a portion of a MIMO packet data signal transmission;
- signal combiner means for combining said at least first and second frequency converted signals to provide at least one combined signal;
- and
- output signal converter means for converting said at least one combined signal to a plurality of data signals having a common nominal frequency and including data samples corresponding to said at least first and second data streams.
A method of converting a multiple input, multiple output (MIMO) packet data signal transmission to a plurality of data samples, comprising:
- converting, in accordance with at least first and second local oscillator (LO) signals, at least first and second RF signals to at least first and second frequency converted signals, wherein said at least first and second RF signals have a common RF carrier frequency, include at least first and second data streams, and form at least a portion of a MIMO packet data signal transmission;
- combining said at least first and second frequency converted signals to provide at least one combined signal;
- and
- converting said at least one combined signal to a plurality of data signals having a common nominal frequency and including data samples corresponding to said at least first and second data streams.
