I'm using atmega32 and Tx/Rx 433Mhz wireless Modules. on the Tx side i measure the temperature which is received on the Rx side where it is being displayed on LCD.I'm using the ADC 10-bit mode of the atmega32 to measure the temperature but i can't get correct result on the LCD Rx side.
They are a very simply ASK (OOK) transmitter/receiver. Even sending digital data, like you would on a serial COM port does not work.
As for your current code, hard wire the two processor's data lines [...]
[...] i was wondering if somebody could give a hint about the best method for noise reduction using this kind of wireless modules??

The noise that you see between transmissions is a direct consequence of how those cheap modules are made - their gain is raised until a signal is received at proper strength (or until it hits the limit), so in the absense of a valid signal, random noise will get through.The only way to cure this noise is by using better (= more expensive) modules, using either FSK- or PSK modulation and perhaps a noise gate.
