Abstract:
A coded light transmission and reception circuit and transmission and reception method use signals to indicate the start and end of a coded light transmission window. Data is modulated onto the current waveform during the transmission window. Each data peak value during said transmission window exceeds an average current in the transmission window (which is used as the decision level) and each valley value during said transmission window is below the average current. In this way, a coded light output can be generated in which the overall decision current varies significantly, but the coded light signal can still be decoded reliably. The average level can be calculated in the receiver and used for demodulating.

Claim (Index 11):
An electronic circuit for receiving data modulated onto a coded light signal, comprising:\n a light receiving element for converting a light input into a current signal having a waveform which varies over time; a detecting circuit for detecting a first current signal indicating a start of a transmission window, and a second current signal indicating an end of said transmission window; and a demodulator for detecting data modulated onto the current waveform during the transmission window, said demodulator is adapted to: detecting an instant value of the current waveform; calculating an average value of the current waveform in the transmission window; and determining a peak value if the instant value is larger than the average value and determining a valley value if the instant value is smaller than the average value, determining the data according to the determined peak values and valley values.
