Space time block coded transmit antenna diversity for WCDMA |
摘要 |
A mobile communication system is designed with an input circuit coupled to receive a first plurality of signals (rj(i+τj), i=0-N-1) during a first time (T0-T1) from an external source and coupled to receive a second plurality of signals (rj(i+τj), i=N-2N-1) during a second time (T1-T2) from the external source. The input circuit receives each of the first and second plurality of signals along respective first and second paths (j). The input circuit produces a first input signal (Rj1) and a second input signal (Rj2) from the respective first and second plurality of signals. A correction circuit is coupled to receive a first estimate signal (alphaj1), a second estimate signal (alphaj2) and the first and second input signals. The correction circuit produces a first symbol estimate ({tilde over (S)}1) in response to the first and second estimate signals and the first and second input signals. The correction circuit produces a second symbol estimate ({tilde over (S)}2) in response to the first and second estimate signals and the first and second input signals.
