There is provided a method for uplink data compression, the method including transforming a signal from a time-domain presentation into a frequency-domain presentation, selecting a group of adjacent frequency bins from the frequency-domain presentation, generating a floating point number representation from values of the group of adjacent frequency bins, wherein the floating point number representation includes a mantissa for each of the frequency bins' values of the group of adjacent frequency bins, and wherein the floating point number representation further includes a common exponent shared between the mantissas, and outputting the mantissas of the floating point number representation, and the value of the common exponent shared between the mantissas of the floating point number representation.
