The equalizer of the present invention operates on input multipath signal samples, preferably at chip or sub-chip resolution, to remove or substantially cancel the effects of one or more secondary signals from the main path signal. Using predetermined path information for one or more of the secondary path signals, including magnitude, phase, and time offset relative to the main path signal, the equalizer compensates input multipath signal samples by subtracting estimated secondary signal values from the input samples. For each input sample, the equalizer forms a sliced sample, where the sliced sample represents a nominal phase value defined by the modulation scheme used in the original chip or symbol transmission that is closest in value to the actual phase of the input sample. These sliced samples are held in a running buffer and used, in combination with the predetermined path information and scaling logic, to form the estimated secondary signal values for compensating the input samples.

A waveguide-implemented antenna comprising a planar array of waveguide slot radiators for communicating electromagnetic signals exhibiting simultaneous dual polarization states. The antenna can consist of parallel ridged waveguides having rectangular or "T"-shaped ridged cross sections. The ridged walls of each parallel ridged waveguide contain a linear array of input slots for receiving (transmitting) electromagnetic signals having a first polarization state from (to) the parallel ridged waveguides and for transmitting (receiving) those signals into (from) a corresponding array of cavity sections. The cavity sections comprise a short section of uniform waveguide with a thickness of much less than a wavelength in the propagation direction. The cavity sections feed to output slots which are rotated relative to the input slots; such that the output slots exhibit a second polarization state, which they radiate (receive) to (from) free space. By interlacing parallel ridged waveguides with alternating +45 degree and -45 degree rotations of the output slots, two independent antennas are formed exhibiting simultaneous dual polarizations. Because the input slots are located in the ridge wall of the parallel ridged waveguides, the parallel ridged waveguides can be fed from their broad wall side. Feeding the parallel ridged waveguides from their broad wall side eliminates a need for a complex feed network.
