To recover the bits from various users in an asynchronous CDMA communications system, samples of the received signal are processed using blocks of code coefficients. Each code coefficient block includes the sequence of code coefficients for each user which formed the received signal samples. Each sequence has the same number of code coefficients and this number is equal to the product of a predetermined number of bit intervals and the number of code coefficients per bit interval. Processing of the received signal samples using this block formation completely eliminates interference including the so-called leading and lagging edge effects and can be implemented with blocks that include the code coefficients in one or more bit intervals. |
