Patent ID: 7099376

Claim:
A method for parallel type interference cancellation in a CDMA receiver, the method comprising the steps of: (a) when an over-sampled position of a received signal reaches the end of a symbol of a user, completing temporary detecting and recovering the symbol of the user; (b) generating a residual signal by using the recovered signal of the user and a received signal state; and (c) detecting symbol information by obtaining an interference cancelled signal by adding the residual signal to the recovered signal of the user, wherein the step (a) includes: (a1) checking whether the end of the symbol of the user is received, and, if the end of the symbol of the user is not received, receiving a signal; and, otherwise, performing temporary detecting for the symbol of the user, and (a2) obtaining the recovered signal by adjusting the amplitude and the phase information of the temporarily detected signal.
