ABSTRACT:
In a CDM (code division multiplex) communications system a base station transmits a plurality of data signals on a common channel. Each data signal is provided with a spreading sequence, e.g. a Gold code, each sequence being allocated to a user of that channel. Each receiver incorporates a channel estimator for determining the channel impulse response (CIR) and means for convolving the CIR estimate with the corresponding user code. This is then correlated with the received signal to recover the received data. The arrangement allows an increased number of users to share a common channel.
