1. A time division multiple access wireless communication system, comprisinga repeated pattern of three cells, each cell having a base station;

  • anda user station;

    wherein said base station and said user station communicate using time division multiple access;

    wherein transmitters in a first cell are assigned a first spread-spectrum code for modulating radio communication in said first cell;

    whereby radio signals used in said first cell are spread across a bandwidth sufficiently wide that receivers in a second cell, said second cell being adjacent to said first cell, may distinguish communication which originates in said first cell from communication which originates in said second cell; and

    whereby said first spread-spectrum code is reused in a plurality of cells such that said first cell in said pattern using said first spread-spectrum code is not adjacent to any other cell using said first spread-spectrum code.
