Polar to Rectangular conversion

Discussion in 'VHDL' started by Alexander Weddell, Nov 28, 2003.

  1. Hi,

    I'm currently working on a university project where I am implementing a form
    of amplifier on an FPGA.

    Basically I've got to the stage where I need to convert a stream of values
    from magnitude-angle form to real-complex. I've been doing a bit of research
    and have discovered the CORDIC algorithm. However, it seems that I need to
    use a rather large look-up table in order to implement it with any accuracy.

    I'd be interested to hear if anyone has experience of implementation of
    this, or any other algorithm, for this purpose. Does anyone know an
    alternative efficient way to convert from polar to rectangular?


    Kind regards,
    Alex.
