Consider a light source emitting a series of pulses equally distanced from one another. A stationary observer (receiver) measures the frequency of the pulses:

The observer starts moving with constant speed towards the light source - the measured frequency increases:

The following quotation is relevant:

http://www.einstein-online.info/spotlights/doppler
Albert Einstein Institute: "By observing the two indicator lights, you can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, the distances between subsequent pulses are not affected, but still there is a frequency shift: As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened. In this particular animation, which has the receiver moving towards the source at one third the speed of the pulses themselves, four pulses are received in the time it takes the source to emit three pulses."

Since "four pulses are received in the time it takes the source to emit three pulses", the speed of the pulses relative to the receiver (observer) is greater than their speed relative to the source, in violation of Einstein's relativity.

"vO is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + vO. [...] The motion of an observer does not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time."

"Let's say you, the observer, now move toward the source with velocity vO. You encounter more waves per unit time than you did before. Relative to you, the waves travel at a higher speed: v'=v+vO. The frequency of the waves you detect is higher, and is given by: f'=v'/λ=(v+vO)/λ."

That is, when the observer starts moving towards the light source with speed v, the speed of the light relative to him becomes c'=c+v, in violation of Einstein's relativity. If so, the frequency the observer measures will become f'=c'/λ, and Doppler effect experiments confirm this prediction.
