Reduction of linear interference canceling scheme

An interference cancellation method for canceling the interference on a data sequence, said method comprising the steps of:

• receiving the data sequence;
• detecting an estimate of a first spreading code's symbols from said data sequence using an interference cancellation unit (ICU);
• storing the estimate of said first spreading code's symbols in a first register associated with said first spreading code's symbols;
• detecting an estimate of a second spreading code's symbols from said data sequence;
• storing the estimate of said second spreading code's symbols in a second register associated with said second spreading code's symbols;
• and
• subtracting signals associated with the estimate of said first spreading code's symbols and said second spreading code's symbols from said data sequence to produce a modified data sequence.

An interference cancellation system for canceling interference on a data sequence, said system comprising:

• a first register and a second register for temporarily storing said data sequence;
• a switch coupled between said first register and said second register for transferring said data sequence from said first register to said second register at predetermined time intervals;
• an interference cancellation unit (ICU) coupled to an output of said second register for receiving the data sequence and detecting estimates of spreading codes's symbols;
• output registers for storing the estimates of said spreading codes' symbols, each of said output registers being associated with one of said spreading codes symbols, said output registers being adapted to accumulate subsequent estimates said spreading codes' symbols;
• and
• subtraction means for subtracting signals associated with the estimates of said spreading codes' symbols from said data sequence, thereby removing the influence of the estimates of said spreading codes' symbols from said data sequence.
