Patent ID: 8340021

Claim:
A wireless communication unit, comprising: a baseband module; a radio frequency module; a communication interface connecting said baseband module to said radio frequency module, for communicating data from said baseband module to said radio frequency module and/or vice versa; wherein: said communication interface includes at least one data compression arrangement, for compressing original data to be transmitted over the communication interface, from a transmitting side of the communication interface to a receiving side of the communication interface, into compressed data and decompressing said compressed data after transmission and restoring the original data, said data compression arrangement including: a data compression unit at said transmitting side of the communication interface, and a data decompression unit at said receiving side of the communication interface; said original data comprises a plurality of pairs of I-values and Q-values, each member of each pair of the plurality of pairs comprising a sequence of bits of length x; and said compressing comprises: calculating a minimum value of I 2 +Q 2 over all of the plurality of pairs of I-values and Q-values; for each position of a bit from 1 to x, determining a threshold, where 1 represents the most significant position and x represents the least significant position; determining that the minimum value exceeds a threshold for a jth position; and removing from each sample of a plurality of samples in said original data the bits from the jth position to the xth position.
